If a dead wilt plant irrigated, it regain its turgidity
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Answer and Explanation: When plants are watered root hairs/ roots absorb water by osmosis and the cells of plants become turgid, the leaves receive the water and become firm again and the plan will be upright and/or assume an erect posture.

Detailed explanation-2: -Interestingly, wilting also serves to reduce water loss, as the drooping leaves expose less surface area to the sun’s evaporative rays. Most plants recover quickly when given water, though prolonged dehydration can be fatal or cause leaf death.

Detailed explanation-3: -Water the plant and the stems stand back up again. Nerve plant (Fittonia) react to lack of water in a similar way. But some plants are more sensitive and won’t revive as quickly. All plants suffer when they dry out too much, but it’s a matter of how soon they get water that determines if they will live or die.

Detailed explanation-4: -Temporary Wilting During hot summer days, small plants and herbaceous plant wilt due to the result of high transpiration rate causing water deficiency in the cells. These plants regain water and normal turgidity in night as temperature decreases. This is called as temporary or transient wilting.
