Given ahead is the diagram of an experimental set up to study the process of transpiration in plants. Study the same and then answer the questions that follow:

Given ahead is the diagram of an experimental set up to study the process of transpiration in plants. Study the same and then answer the question that follow:
After about half an hour what change, if any, would you expect to find in the cobalt chloride paper placed on the dorsal and ventral sides of the leaf? Give a reason to support your answer.
The apparatus shown in the following diagram is Garreau’s potometer designed to demonstrate unequal transpiration from the two surfaces of a dorsiventral leaf. Before keeping the leaf in between the cups, anhydrous calcium chloride (CaCl2) contained in two small vials were weighed and placed in both the cups. The ends of the cups were closed with corks through which two mercury manometers were connected. After few hours, CaCl2 vials were taken out and weighed again.
What do you mean by transpiration?
Differentiate Between Cobalt chloride paper and Goat’s bladder.

(iv) Mention two structural features of A, which help in the function mentioned in (iii) above.
(v) Where is this structure likely to be found in a leaf?
(vi) The above structure helps in the process of transpiration. Explain the term transpiration.

The ends of the cups were closed with corks through which two mercury manometers were connected. After a few hours, CaCl2 vials were taken out and weighed again.
(i) What is the purpose of keeping CaCl2 vials inside the cup?
(ii) After a few hours, the CaCl2 vials were taken out and weighed again. Will you expect any difference in weight? If so, give reasons.
(iii) What was the purpose of using a mano-meter?
(iv) What do you mean by transpiration?
