Question

In some plants, the leaves droop down during day, while become normal during night

• A. Due to temporary wilting
• B. Permanent wilting
• C. Both A and B
• D. None of the above

Answer 1

Answer: (A)

Due to temporary wilting

Temporary wilting is caused when the rate of transpiration is more than the rate of absorption of water and so, cells of leaves will lose their turgor. However, the turgidity of leaf cells can be restored by watering the plants or when the rate of transpiration falls during night time.

So, the correct answer is option A.
