Answer 2

There is folding of leaves during the absence of water at the time of drought.

Explanation:

• when there is complete absence of water there is the growth of a special type of cell known as bulliform cell. This cells results in the folding of the leaves.

• As a result of this there is is negligible or no transpiration from the leaves because of the obstruction of the stomata due to folding. Hence there is no loss of water by the plant. So water is retained.
