Solution
The correct option is C Incipient wilting
Wilting is the loss of turgidity of leaves and other soft aerial parts of a plant causing their drooping, folding and rolling.
In incipient wilting, the mesophyll cells have lost sufficient water due to transpiration but no external signs of wilting can be seen.
Temporary wilting is the temporary drooping down of leaves and young shoots due to loss of turgidity during noon. It can be corrected in the evening after the rate of transpiration decreases accompanied by replenishment of water around root hairs.
Permanent wilting is that state in the loss of turgidity of leaves when they do not regain their turgidity even on being placed in a suitable atmosphere.
Thus, the correct answer is option (C).
