Due to temporary wilting

Vedclass · Answer

(A) The phenomenon described is temporary wilting. It is the temporary drooping down of leaves and young shoots due to the loss of turgidity during the noon hours. At this time,the rate of transpiration is at its maximum. Temporary wilting is corrected only after the rate of transpiration decreases in the afternoon,accompanied by the replenishment of water around the root hairs.

In some plants,the leaves drop down during the day while becoming normal during the night.
