Determiners are words that come before nouns. They contain several classes of words, including pronouns and adjectives. They determine or limit the noun by giving some additional information about it. Determiners show whether a noun refers to is a general or a specific object, person, or place. They indicate which or how many things the noun refers to. Determiners define or limit a noun to the singular or plural. They indicate the amount or quantity. Determiners and nouns together make noun phrases. They make noun phrases with adjectives too. Determiners may precede numerals too.

CBSE Class 12 Case Studies In Business Studies – Principles of Management

PRINCIPLES OF MANAGEMENT
Principles of Management: Definition
The principles of management serve as broad and general guidelines for the managerial decision making and action.

Types of Principles of Management

1. Fayol’s Principles of General Management
2. Taylor’s Principles of Scientific Management.

Significance of Principles of Management

1. They help to provide managers with useful insights into reality and increase their efficiency in dealing with recurring problems.
2. They ensure optimum utilisation of resources as due to the presence of cause and effect relationship the outcome of the decisions and actions can be predicted. Moreover, it leads to effective administration as the principles tend to restrict the personal prejudices and biases.
3. They facilitate scientific decision making as they emphasise on logical thinking rather than blind faith.
4. They help to meet the changing requirements of the environment to the best advantage ofa organisation.
5. They help in fulfilling social responsibility of an organisation.
6. They facilitate the process of management training, education and research as they are at the core of management theory.

Features of Principles of Management

1. Universal Applicability: The principles of management are deemed to apply to all types and sizes of organizations.
2. General Guidelines: The principles are guidelines to action but do not provide readymade, straitjacket solutions to all managerial problems as the real business situations are very complex and dynamic and are a result of many factors.
3. Formed by practice and experimentation: The principles of management are formulated by the management experts through observation and tested through repeated experimentation.
4. Flexible: The principles of management are not rigid prescriptions, which have to be followed absolutely. They are flexible and can be modified by the manager in the light of given situation so as to achieve the desired goals.
5. Mainly Behavioural: The principles of management aim at influencing behaviour of human beings in a desired manner.
6. Cause and effect relationships: The principles of management seek to establish relationship between cause and effect so that they can be used in similar situations in a large number of cases.
7. Contingent: The application of principles of management is contingent or dependent upon the prevailing situation at a particular point of time.

FAYOL’S PRINCIPLES OF MANAGEMENT

1. Division of work: The whole organisation work, both managerial and technical, should be divided into smaller jobs and the task involved in doing each such job should be determined. It leads to specialization, speed, efficiency and accuracy of work.
2. Discipline: It refers to the obedience to organizational rules and the employment agreement. It is necessary for the systematic working of the organisation. It requires good superiors at all levels, clear and fair agreements and judicious application of penalties.
3. Authority and Responsibility: There should always be a balance between the authority given and responsibility entrusted to an employee. This is because if authority is more than responsibility, the employees are likely to misuse it whereas if authority is less than responsibility, he/she will be unable to do the desired work.
4. Unity of command: There should be one and only one boss for every individual employee from whom he should receive orders and be responsible to. Dual subordination should be avoided.
5. Unity of Direction: All the units of an organisation should be moving towards the same objectives through coordinated and focused efforts. Each group of activities having the same objective must have one head and one plan.
6. Subordination of Individual Interest to General Interest: In all the situations, the interests of an organisation should take priority over the interests of any one individual employee .
7. Remuneration of employees: The overall pay and compensation should be fair to both employees and the organization. The employees should be paid fair wages, which should give them at least a reasonable standard of living. At the same time it should be within the paying capacity of the company i.e. remuneration should be just and equitable.
8. Centralisation and Decentralisation: The concentration of decision-making authority is called centralisation whereas its dispersal among more than one person is known as decentralization. Large organizations have more decentralization than small organizations.
9. Scalar Chain: The formal lines of authority along which the communication flows from highest to lowest ranks are known as scalar chain. Gang Plank is a shorter route that has been provided so that communication is not delayed during emergencies. However, the superior has to be informed later on.
10. Order: The people and materials must be in suitable places at appropriate time for maximum efficiency i.e. ‘a place for everything (everyone) and everything in its place/
11. Equity: It emphasizes kindliness and justice in the behaviour of managers towards workers. No discrimination should be made by them on the basis of caste, creed, gender or otherwise caste, creed.
12. Stability of Personnel: The employee turnover should be minimized to maintain organizational efficiency. Personnel should be selected and appointed after due and rigorous procedure. After placement, they should be kept at their post for a minimum fixed tenure so that they get time to show results. Any adhocism in this regard will create instability/insecurity among employees. They would tend to leave the organisation.
13. Initiative: Initiative means taking the first step with self-motivation. The workers should be encouraged to develop and carry out their plans for improvement. Suggestion system should be adopted in the organization.
14. Espirit De Corps: The management should promote a team spirit of unity and harmony among employees. A manager should replace T with ‘We’ in all his conversations with workers.

Difference between Unity of Comman and Unity fo Direction

S.No.	Basis	Unity of Command	Unity of Direction
1.	Meaning	One subordinate should receive orders from and should be responsible to only one superior.	Each group of activities having same objective must have one head and one plan.
2.	Aim	It prevents dual subordination.	It prevents overlapping of activities.
3.	Implications	It affects an individual employee	It affects the entire organization.

SCIENTIFIC MANAGEMENT
Scientific Management: Definition
Scientific Management means knowing exactly what you want your employees to do and seeing that they do it in the best and cheapest way.
Fredrick Winslow Taylor is known as the ‘Father of Scientific Management’.

Techniques of Scientific Management

1. Time Study is the technique to determine the standard time taken bya worker of average skill and knowledge to complete a standard task.
2. Fatigue study seeks to determine the amount and frequency of rest intervals required in completing a task.
3. Method study seeks to find out one best way of doing the job.
4. Motion study refers to the study of movements of limbs which are undertaken while doing a typical job.This helps to eliminate unnecessary movements so that it takes less time to complete the job efficiently.
5. Standardisation refers to the process of setting standards for every business activity Simplification aims at eliminating superfluous varieties, sizes and dimensions of products.
6. Functional foremanship is an extension of the principle of division of work and specialisation to the shop floor. Each worker is supposed to take orders from eight foremen in the related process or function of production namely
   • Instruction Card Clerk: He assigns work to all the employees.
   • Route Clerk: He decides how work will progress regarding total productions. So that production is on time.
   • Time and Cost Clerk: He determines what will be the total cost and how much time each job take.
   • Disciplinarian: He sees that there is discipline at work place.
   • Speed boss: He ensures that the work is moving at a suitable pace.
   • Gang Boss: He ensures sufficient availability of raw material, tools etc.
   • Repair Boss: He sees that whenever some repair is involved in any work, the work is done properly.
   • Inspector: He sees that whether the quality of output is good or not.
7. Differential piece wage system was introduced to reward efficient workers by paying them at a higher rate than those who performed below standard.

PRINCIPLES OF SCIENTIFIC MANAGEMENT

1. Science not Rule of Thumb
   • Taylor believed that there was only one best method to maximise efficiency which can be developed through study and analysis and should substitute ‘Rule of Thumb’ or hit and trial method throughout the organisation.
   • The scientific method involved investigation of traditional methods through work-study unifying the best practices and developing a standard method, which would be followed throughout the organisation.
   • In the present context, the use of internet has brought about tremendous improvements in internal efficiencies and customer satisfaction.
2. Harmony, Not Discord
   • Taylor emphasised that there should be complete harmony between the management and workers instead ofa kind of class-conflict, the managers versus workers.
   • To achieve this state, Taylor called for complete mental revolution on the part of both management and workers.
   • The prosperity for the employer cannot exist fora long time unless it is accompanied by prosperity for the employees and vice versa.
   • He advocated paternalistic style of management should be in practice.
3. Cooperation, Not Individualism
   • This principle is an extension of principle of ‘Harmony Not Discord’
   • There should be complete cooperation between the labour and the management instead of individualism.
   • Competition should be replaced by cooperation and there should be an almost equal division of work and responsibility between workers and management.
   • Also, management should reward workers for their suggestions which results in substantial reduction in costs.
   • At the same time workers should desist from going on strike and making unreasonable demands on the management
4. Development of Each and Every Person to His or Her Greatest Efficiency and Prosperity
   • Taylor was of the view that the concern for efficiency could be built in right from the process of employee selection.
   • Each person should be scientifically selected and the work assigned should suit her/his physical, mental and intellectual capabilities.
   • To increase efficiency, they should be given the required training.
   • Efficient employees would produce more and earn more. This will ensure their greatest efficiency and prosperity for both company and workers.

Latest CBSE Questions

Question 1.
Explain ‘unity of command’ and ‘equity’ as principles of general management. (CBSE, Delhi 2017)
Answer:

1. Unity of command: According to Fayol, there should be one and only one boss for every individual employee. Dual subordination should be avoided. Fayol felt that if this principle is violated “authority is undermined, discipline is in jeopardy, order disturbed and stability threatened”.
2. Equity: According to Fayol, “Good sense and experience are needed to ensure fairness to all employees, who should be treated as fairly as possible.” This principle emphasizes on kindliness and justice in the behaviour of managers towards workers. The managers should not discriminate against anyone on account of gender, religion, language, caste, belief or nationality etc.

Question 2.
Sanchit, after completing his entrepreneurship course from Sweden returned to India and started a coffee shop ‘AromaCoffeeCan’ in a famous mall in New Delhi. The speciality of the coffee ship was the special aroma of coffee and a wide variety of flavours to choose from. Somehow, the business was neither profitable nor popular. Sanchit was keen to find out the reason. He appointed Sandhya, an MBA from a reputed college, as a Manager to find out the causes for the same.
Sandhya took feedback from the clients and found out that though they loved the special unique aroma of coffee but were not happy with the long waiting time being taken to process the order. She analysed and found out that there were many unnecessary obstructions in between which could be eliminated. She fixed a standard time for processing the order.
She also realised that there were some flavours whose demand was not enough. So, she also decided to stop the sale of such flavours. As a result with in a short period Sandhya was able to attract the customers.
Identify and explain any two techniques of scientific management used by Sandhya to solve the problem. (CBSE, Delhi 2017)
Answer:
The two techniques of scientific management used by Sandhya to solve the problem are: (any two)

1. Time study: It seeks to determines the standard time taken to perform a well-defined job. The objective of time study is to determine the number of workers to be employed , frame suitable incentive schemes and determine labour costs. By using time measuring devices for each element of task the standard time is fixed for the whole of the task by taking several readings.
2. Simplification (Standardisation and Simplification): Simplification aims at eliminating superfluous diversity of products in terms of varieties, sizes and dimensions. It not only helps to reduce inventories but also save cost of labour, machines and tools. Thus it helps to increase turnover by ensuring optimum utilisation of resources.
3. Motion study: Motion study refers to the study of movements of limbs of a worker while doing a particular task. It seek to divide all such movements into three categories namely;
   • Motions which are required
   • Motions which are unnecessary
   • Motions which are incidental.
     Thus, motion study helps to eliminate unnecessary movements of a work and enables him to complete the given task efficiently.

Question 3.
Explain briefly ‘discipline’ and ‘scalar chain’ as principles of general management. (CBSE, Delhi 2017)
Answer:

1. Discipline: Discipline refers to the obedience to organisational rules and employment
   agreement which are necessary for the working of the organisation. According to Fayol, discipline requires good superiors at all levels, clear and fair agreements and judicious application of penalties. .
2. Scalar chain: According to Fayol the formal lines of authority from highest to lowest ranks are known as scalar chain. He suggests that the,”Organisations should have a chain of authority and communication that runs from top to bottom and should be followed by managers and the subordinates.” However in order to ensure speedy communication during emergencies, Gang Plank is a shorter route that has been provided . However, the superior has to be informed later on.
   
   For example in the following case there is one head ‘A’ who has two lines of authority under her/ him. One line consists of B-C-D- E-F. Another line of authority under ‘A’ is L-M-N-O-P. If ‘E’ has to communicate with ‘O’ who is at the same level of authoritythen she/he has to traverse the route E-D-C-B-A-L-M-N-O. This is due to the principle of scalar chain being followed in this situation. However, if there is an emergency then ‘E’ can directly contact ‘O’ through ‘Gang Plank’ as shown in the diagram. But they should inform their superiors about it later on.

Question 4.
Explain ‘order’ and ‘initiative’ as principles of general management. (CBSE, Delhi 2017)
Answer:

1. Order: According to Fayol, “People and materials must be in suitable places at appropriate time for maximum efficiency.” The principle of order states that ‘A place for everything (everyone) and everything (everyone) in its (her/his) place’. A sense of orderliness will lead to increased productivity and efficiency in the organization.
2. Initiative: Initiative means taking the first step with self-motivation. The workers should be encouraged to develop and carry out their plans for improvement. Suggestion system should be adopted in the organization.

Question 5.
Explain briefly ‘Unity of Direction’ and ‘Order’ as principles of general mangement. (CBSE, OD 2017)
Answer:

1. Unity of direction: According to Fayol, each group of activities having same objective
   must have one head and one plan. It prevents overlapping of activities. For example if a company is manufacturing handmade carpets as well as machine made carpets there is likely to be a lot of overlapping of activities. Therefore, there should be two separate divisions for both of them wherein each division should have its own in charge, plans and execution resources.
2. Order: According to Fayol, “People and materials must be in suitable places at appropriate time for maximum efficiency.” The principle of order states that ‘A place for everything (everyone) and everything (everyone) in its (her/his) place’. A sense of orderliness will lead to increased productivity and efficiency in the organization.

Question 6.
Explain briefly ‘Initiative’ and ‘Esprit de Corps’ as principles of general mangement. (CBSE, OD 2017)

1. Initiative: Initiative means taking the first step with self-motivation. The workers should’ be encouraged to develop and carry out their plans for improvement. Suggestion system should be adopted in the organization.
2. Espirit de corps: According to Fayol, ‘Management should promote a team spirit of unity and harmony among employees.” A manager should replace T with ‘We’ in all his conversations with workers to promote teamwork. This approach is will give rise to a spirit of mutual trust and belongingness among team members. It will also reduce the need for using penalties.

Question 7.
Explain briefly ‘Remuneration of Employees’ and ‘Scalar Chain’ as principles of general mangement. (CBSE, OD 2017)
Answer:

1. Remuneration of employees: According to Fayol, the overall pay and compensation should be fair and equitable to both employees and the organisation. The employees should be paid fair wages so that they are able to maintain at least a reasonable standard of living. At the same time it should be within the paying capacity of the company. This will ensure pleasant working atmosphere and good relations between workers and management.
2. Scalar chain: According to Fayol, the formal lines of authority from highest to lowest ranks are known as scalar chain. He suggests that the,”Organisations should have a chain of authority and communication that runs from top to bottom and should be followed by managers and the subordinates.” However in order to ensure speedy communication during emergencies, Gang Plank is a shorter route that has been provided . However, the superior has to be informed later on.
   
   For example in the following case there is one head ‘A’ who has two lines of authority under her/him. One line consists of B-C-D- E-F.
   Another line of authority under ‘A’ is L-M-N- O-P. If ‘E’ has to communicate with ‘O’ who is at the same level of authority then she/he has to traverse the route E-D-C-B-A-L-M-N-O.
   This is due to the principle of scalar chain being followed in this situation. However, if there is an emergency then ‘E’ can directly contact ‘O’ through ‘Gang Plank’ as shown in the diagram.

For example, Mehul tells Neeraj that he might get tempted to misuse his powers for his or his family’s benefit and so he must display exemplary behaviour to raise his stature in the eyes of the company.
   • Scalar Chain: According to Fayol, the formal lines of authority from highest to lowest ranks are known as scalar chain. He suggests that “The organisations should have a chain of authority and communication that runs from top to bottom and should be followed by managers and the subordinates.” However, in order to ensure speedy communication during emergencies, Gang Plank is a shorter route that has been provided.

Answer:

1. The various principle of scientific management that Hritik plans to apply in his business are described below:
   • Science, not Rule of Thumb: Taylor believed that there was only one best method to maximise efficiency and it could be developed through scientific study and analysis. This is because if the managers rely on personal judgment in attending to the work related problems, it may suffer from the limitation of a trial and error approach. Therefore, it is important for them to know what works and why does it work. For this, they should adopt scientific method to substitute the ‘Rule of Thumb or hit and trial method’ throughout the organisation.
   • Harmony, Not Discord: In the paternalistic style of management, the employer takes care of the needs of employees like a father. Taylor said that any kind of class conflicts between the workers and the managers were not good; rather they must realise that each one is important. Therefore, he emphasised that there should be complete harmony between the management and workers. To achieve this, Taylor called for complete mental revolution on the part of both management and workers by transforming their thinking. The management should share the gains of the company, if any, with the workers and at the same time, workers should work hard.
   • Cooperation, Not Individualism: Through this principle, Taylor suggests that there should be complete cooperation between the workers and the management instead of individualism. This principle is an extension of principle of ‘Harmony, Not Discord’. Both should realise the importance of each other. In order to replace the feeling of competition with cooperation, the management should not close its ears to any constructive suggestions made by the employees. Rather, the workers should be rewarded for any of their valuable suggestions which results in substantial saving in costs. Also, the workers should be taken into confidence by the management whenever any important decisions are to be taken.

In order to establish standards of excellence and quality in materials and in the performance of men and machines, the company adheres to benchmarks during production. Moreover, its products are available in limited varieties, sizes and dimensions thereby eliminating superfluous diversity of products.
Identify the technique of scientific management which has been adopted by ‘Study Buddy Pvt. Ltd.’
Answer:
Standardisation and Simplification of Work is the technique of scientific management which has been adopted by ‘Study Buddy Pvt. Ltd.’
Standardisation implies devising new varieties instead of the existing ones. It refers to the process of setting standards for every business activity; it can be standardisation of process, raw material, time, product, machinery, methods or working conditions. These standards are the benchmarks which must be adhered to during production. It helps to reduce a given line or product to fixed types, sizes and characteristics, establish interchange ability of manufactured parts and products, determine standards of excellence and quality in materials and of performance of men and machines.
Simplification aims at eliminating superfluous diversity of products in terms of varieties, sizes and dimensions. It not only helps to reduce inventories but also to save cost of labour, machines and tools. Thus it helps to increase turnover by ensuring ‘optimum utilisation of resources. Most large companies like Samsung, Toyota and Microsoft etc. have successfully implemented standardisation and simplification.

Question 10.
Anshul owns a small scale factory where utility items are prepared from waste material like paper mache items, paper and cloth bags, decorative material etc. Over the past few weeks, he was observing that the productivity of one of his very efficient worker, Ramdas, is going down. So he decides to probe into the matter and confronts Ramdas one day. On being asked, Ramdas shares with Anshul that he has deliberately slowed down in his work as many of the less efficient workers often pull his leg saying that there is no need for him to be more efficient when everybody is being paid at the same rate. Taking a lesson from this insight, Anshul decides to implement an incentive bonus plan so as differentiate between efficient and inefficient workers.
In context of the above case:

1. Name and explain the incentive bonus plan that Anshul may implement so as differentiate between efficient and inefficient workers.
2. State any two values that Anshul wants to communicate to the society by setting up a special type of business.

Answer:
Differential Piece Wage System is the incentive bonus plan that Anshul may implement so as differentiate between efficient and inefficient workers.
Differential Piece Wage System is a performance based wage system which was introduced by Taylor so as to distinguish between the workers who were able to achieve the standard or performed above standard from those who performed below standard. For example, it is determined that standard output per worker per day is 10 units and those who made standard or more than standard will get Rs. 40 per unit and those below will get Rs. 30 per unit. Now an efficient worker making 11 units will get 11 x 40 = Rs. 440 per day whereas a worker who makes 9 units will get 9 x 30 = Rs. 270 per day. According to Taylor, the difference of Rs. 170 should be enough for the inefficient worker to be motivated to perform better.

Question 11.
Swaraj is running an office furniture showroom. Most of his clients are businessmen and they prefer to buy goods on credit. Keeping this in mind, he has given the power to the sales manager, Mr. Bhardwaj, to offer a credit period of only 20 days, while negotiating a deal with a buyer. On a specific day, Mr. Bhardwaj finds that if he can offer a credit period of 30 days as an exception to a prospective buyer, he is likely to finalise a highly profitable deal for the business. So Mr. Bhardwaj requests Swaraj to grant him additional authority for offering a credit period of 30 days in the interest of the business. But Swaraj refuses to extend his authority and as a result, the deal is not finalized.
In context of the above case:

1. Can Mr. Bhardwaj be held responsible for loss of the deal? Why or why not ? Give a suitable reason in support of your answer.
2. Also, explain the related principle.

Answer:

1. No, Mr. Bhardwaj cannot be held responsible for loss of the deal in the above case as he was not given the necessary authority to carry out his responsibility. There is an imbalance in authority and responsibility.
2. The name of the related principle is Authority and Responsibility.
   Authority is the right to give orders and obtain obedience by the virtue of one’s position in the organization. Responsibility is the obligation of a person to carry out the assigned task to the best of one’s abilities and skills. There are two types of authorities, namely the official authority, which is the authority to command, and personal authority, which is the authority of the individual manager. Authority is both formal and informal. According to Fayol, there should be balance between the authority given and responsibility entrusted to an employee so that he is able to carry out the assigned task. Any kind of imbalance in authority and responsibility is not good for the organisation. If the authority granted to an employee is less than what is required, he will ineffective in doing his work. On the other hand, if the authority delegated to an employee is more than what is required, he may tend to misuse it.

Long Answer (Value Based) Type Questions [8 Marks each]

Question 1.
Mme Loisel’s disposition invites her doom. Comment in the context of the text you’ve read.
or
What kind of person is Matilda Loisel?
Support your answer giving examples from the story “The Necklace”.
Answer:
Mme Loisel belongs to a family of clerks. Her existence is quite average. They live on meagre income, enough for basic needs but not to fulfil aspirations. She gets married to a clerk and is so caught up with her dreams of wealth and pleasure that she is out of touch with the truths of her real life. In order to keep up appearances just to flatter her pride, she blows up four hundred francs on a gorgeous dress. And, not contented, she goes on borrowing a necklace from her friend. And, all of this is just to impress the wealthy and the rich with her beauty and glamour (even if on loan). No doubt, her pride is flattered and her wish of fine dining, expensive dresses and jewels satisfied but at a great price. Unfortunately, the necklace has lost and the couple has to cough up their entire inheritance and borrow as well to replace it. Repayment of the debt eats away the next ten years of their youth. They live poor. All the house hold chores and cares of a life of poverty visit them. Hence, her disposition invites her doom.

Question 2.
Mme Forestier proved to be a true friend. Elucidate. [CBSE2015]
Answer:
Mme Forestier turns out to be an interesting character. She plays a very vital role in the story. As a friend to Matilda, we find her to be really genuine as she helps Matilda in the hour of her need. When Mme Loisel needs to borrow jewels, she turns to Mme Forestier. Mme Forestier does not refuse. Displaying her generosity, she opens up the entire array of her jewels for Matilda to choose from. Also, she is considerate when Loisels delay the return of the necklace. Surprisingly, at the end of the story, she concludes the entire narrative.
Without even a moment’s hesitation, she reveals to Matilda that her necklace was just a fake. She is not at all worried in the light of the fact that she may have to return the necklace. It shows her honesty. Rather, she, like a true friend, feels bad for Matilda at her unnecessary suffering. We find her sympathising with Mme Loisel. She is indeed a gem of a friend.

Question 3.
Do you think the story is aptly titled? Justify your answer.
Answer:
The whole narrative of the story ‘The Necklace’ revolves around a young woman Matilda, who in her foolish pride borrows a necklace inviting misery and sorrow for herself as well as for her husband. The ‘necklace’ has lost and the Loisels fall into a tremendous debt. They spend the next ten years of their life in paying debt for the replacement of the lost necklace. Their entire life moves around impoverished everyday saga of misery and hunger and the necklace, in fact, changes the very course of their life. Also, it is against the back drop of the necklace that Matilda’s pride and dishonesty are highlighted. At the same time, the necklace serves a twist at the end as it turns out to be a fake one. The story is, hence, most aptly titled as the necklace is, in fact, the leading character of this ironic tale of desire, the doom and the tragedy.

CBSE Class 10 Science Practical Skills – CO₂ is Released During Respiration

BASIC BUILDING CONCEPTS
Respiration is of two types – aerobic respiration and anaerobic respiration.

1. Aerobic respiration – In this type of respiration oxygen is utilised. As a result, complete oxidation of glucose takes place and maximum amount of energy is released. This type of respiration can be represented by the following equation:
   
   Aerobic respiration involves three stages-Glycolysis, Krebs cycle and ETS. All the events associated with glycolysis occur in cytoplasm and events associated with Kreb cycle and ETS take place in mitochondria.
2. Anaerobic respiration – In this type of respiration food is oxidised in the absence of oxygen. In this case, incomplete oxidation of glucose results in release of lesser amount of energy. The process of anaerobic respiration can be represented by the following equations:
   

AIM
To show experimentally that carbon dioxide is given out during respiration,

MATERIALS REQUIRED
Conical flask, U-shaped delivery tube (tube bent twice at right angles), cotton wool or moist blotting paper, water, thread, beaker, test tube, rubber cork with one hole, 20% freshly prepared KOH solution, vaseline, soaked gram seeds.

THEORY
Respiration is a biochemical process during which food (glucose) is oxidised to liberate energy. It is a catabolic process.
In the experiment, moist gram seeds are taken as they are actively respiring and releasing CO₂. The CO₂ released is absorbed by KOH and forms KgCO₃.

PROCEDURE

1. Take about 25-30 seeds of gram and germinate these seeds by placing them on moist cotton wool or moist blotting paper for 3-4 days.
2. Place the germinated seeds into a conical flask and sprinkle a little water in flask to moist the seeds.
3. Take freshly prepared 20% KOH solution in a test tube and hang it in conical flask with help of thread.
4. Close the mouth of conical flask by placing a rubber cork containing one hole. .
5. Through the hole of rubber cork, insert one end of the U-shaped glass delivery tube in the conical flask and place the other end into a beaker filled with water.
6. Seal all the connections of the experimental set-up with vaseline so as to make it air-tight.
7. Mark the initial level of water in the U-shaped delivery tube.
8. Keep the apparatus undisturbed for 1-2 hours and note the change in level of water in the delivery tube.

OBSERVATIONS
After sometime, the level of water in U-shaped delivery tube dipped in water of the beaker rises.

RESULT
Germinated gram seeds in a conical flask release CO, during respiration. The C02 released is absorbed by KOH present in the hanging test tube in conical flask. This creates a vacuum in conical flask which causes upward movement of water in the delivery tube leading to change in level of water in the delivery tube.

PRECAUTIONS

1. Germinating seeds should be kept moist.
2. All connections of the set-up should be air-tight.
3. Freshly prepared KOH solution should be used.
4. Keep one end of U-shaped delivery tube in conical flask and the other end immersed in water of the beaker.
5. The test tube containing KOH should be hung carefully.

INTERACTIVE SESSION

Question 1.
What is respiration?
Answer:
Respiration is a biochemical process by which food material is broken down by cells into simple substances such as C02 and energy is released in the process.

Question 2.
What are the types of respiration?
Answer:
The types include-

• Aerobic respiration- Occurs in presence of O₂ and end products are CO, and H₂O.
• Anaerobic respiration- Occurs in absence of O₂ and involves incomplete oxidation.

Question 3.
What is energy output in anaerobic respiration and why is it less than the aerobic respiration?
Answer:
Anaerobic respiration releases 2 ATP, whereas aerobic respiration releases 38 ATP. It is because aerobic respiration involves complete oxidation or breakdown of glucose whereas in anaerobic respiration partial breakdown or oxidation of glucose takes place.

Question 4.
Name the steps involved in aerobic respiration.
Answer:
Steps include : Glycolysis —–> Krebs cycle ——> ETS and Oxidative phosphorylation.

Question 5.
Where do the following reactions occur in a cell – Glycolysis and Krebs cycle?
Answer:
Glycolysis – Cytoplasm of cell
Krebs cycle – Mitochondria.

Question 6.
Name the energy currency of cell.
Answer:
ATP (Adenosine triphosphate).

Question 7.
Does respiration occur in plants along with photosynthesis?
Answer:
Yes, plants also respire during day along with photosynthesis.

Question 8.
What is Compensation Point?
Answer:
Compensation Point is when the rate of photosynthesis is just equivalent to the rate of respiration so that there is no net gaseous exchange.

Question 9.
Why should the seeds be kept moist during the experiment?
Answer:
Germinating seeds require water for growth. If moisture is not available, the seeds dry up, and rate of respiration would fall.

Question 10.
What would happen if instead of moist germinating seeds, boiled seeds are used for experiment?
Answer:
Boiled seeds do not respire and hence, no result will be obtained.

Question 11.
How does the use of KOH help to show that C02 is released during respiration in the above experiment?
Answer:
KOH solution absorbs the CO₂ released during respiration of seeds, which creates a partial vacuum in the conical flask, causing the rise in the water level of the U-shaped delivery tube. Rise in the level of water shows that CO₂ is released during respiration.

Question 12.
What would happen if test tube containing KOH solution is removed from the conical flask in the set-up?
Answer:
CO₂ released during respiration of seeds will not be absorbed and there will be no rise in the level of water.

Question 13.
Why is vaseline used in the experiment?
Answer:
Vaseline is involved in all the joints in the experimental set-up, thereby making the set-up air-tight.

Question 14.
Suggest an alternate set-up for the experiment to show that CO₂ is released during respiration.
Answer:
Instead of plain water in beaker, lime water can be used. Lime water turns milky with CO₂.

Question 15.
Name the gas absorbed by KOH solution.
Answer:
CO₂

Question 16.
CO₂ is called respiratory gas. Why?
Answer:
Gases involved during respiration are called respiratory gases. They include CO₂ and O₂.

Question 17.
Write an equation to represent aerobic respiration.
Answer:
C₆H₁₂O₆ + 6O₂ ——> 6CO₂ + 6H₂O + 38 ATP

Question 18.
What is fermentation?
Answer:
The anaerobic respiration carried out by some microorganisms in called fermentation.

Question 19.
Give the end products of anaerobic respiration occurring in muscles in humans.
Answer:
Lactic acid and energy (2 ATP).

Question 20.
Why is respiration called a catabolic process?
Answer:
Respiration involves the breakdown of big molecules (e.gcarbohydrates or fats) to smaller molecules.

Question 21.
At what time of the day does plants respire?
Answer:
Plants respire all the time.

Question 22.
Define breathing.
Answer:
Breathing is a physical process of inhalation ( taking in) of oxygen-rich air and exhalation (giving out) of carbon dioxide-rich air.

NCERT LAB MANUAL QUESTIONS

Question 1.
What is the role of KOH in this experiment?
Answer:
KOH absorbs the CO₂ released by germinating seeds leading to creation of partial vacuum.

Question 2.
When we say that plants and animals respire, where exactly is the process occurring?
Answer:
Mitochondria of the cell.

Question 3.
Why do we use germinating seeds in this experiment?
Answer:
Germinating seeds respire actively at a faster rate.

Short Answer Questions

Question 1.
What is respiration? Why is respiration a catabolic process?
Answer:
Respiration is a biochemical process in which food material is broken down into simple substances, like carbon dioxide and energy is released. Respiration involves breakdown of larger molecular (carbohydrates and fats) into smaller molecules. Hence, it is a catabolic process.

Question 2.
Differentiate between aerobic and anaerobic respiration.
Answer:

Question 3.
What would happen if:

1. KOH solution is not hung in conical flask during experiment.
2. seeds are not kept moist during experiment.

Answer:

1. Carbon dioxide released by respiration of seeds will not be absorbed. So, partial vacuum will not be created and thus there will be no rise in the level of water in the glass tube.
2. If moisture is not available, seeds will dry up and rate of respiration would fall.

Question 4.
Why are germinating seeds taken in the experiment? What would happen if germinating seeds are replaced by boiled seeds?
Answer:
As germinating seeds respire actively and at a faster rate, they are taken for the experiment. Boiled seeds do not respire and so no results will be obtained if they replace the germinating seeds in the experiment.

Question 5.
What happens to carbon dioxide given out by germinating seeds while performing the experiment?
Answer:
The carbon dioxide given out by germinating seeds is absorbed by KOH and potassium carbonate is formed.
