The figure given below represents an experimental setup with a weighing machine to demonstrate a particular process in plants. The experimental set-up was placed in bright sunlight. Study the diagram and answer the following questions:

1. Name the process intended for the study.
2. Define the above mentioned process.
3. When the weight of the test tubes (A and B) is taken before and after the experiment, what is observed? Give reasons to justify your observations in A & B.
4. What is the purpose of keeping the test tube B in the experimental set-up?
5. What is the purpose of putting oil in the test tube?

Study the diagram given alongside and answer the questions that follow:

(i) Explain the physiological process of being study.
(ii) What will be the observations in the two test-tubes after about 2-3 days?
(iii) Give a reason for your answer in (ii) above.
(iv) Why is the surface of water covered with oil?
(v) State the purpose of setting up test tube B.

Study the diagram given below and answer the questions that follow:

(i) Name the process being studied in the above experiment.
(ii) Explain the process mentioned in (i) above.
(iii) Why is oil placed over water?

The following diagram is set up to demonstrate an experiment.

Five plants A, B, C, D, and E were placed in a beaker containing water. The water in each beaker was covered with a layer of oil. The leaves were removed from plant D in plant B, upper surfaces of all the leaves were covered with Vaseline, in-plant C the lower surfaces of all the leaves were covered with Vaseline and plant E was exposed to strong light. The beakers were then left for a few hours and at the end of the experimental period, weights of each beaker were taken.
Write the correct answer out of the five available choices given under each question:
I. In which beaker would you expect the greatest decrease in weight?
(i) A (ii) B (iii) C (iv) D (v) E
II. In which beaker the change of weight would be minimum?
(i) A (ii) B (iii) C (iv) D (v) E
III. Which plant would remain healthy for a longer period of time?
(i) A (ii) B (iii) C (iv) D (v) E
IV. In this experiment which plant can be considered as the uncontrolled one?
(I) A (ii) B (iii) C (iv) D (v) E
V. The difference of weight would b maximum between:
(i) A and B (ii) A and C (iii) A and D (iv) A and E (v) D and E
