Question

Despite availability of plenty of water, leaves of certain plants wilt during the day and recover in the evening

Answer 1

Plants frequently wilt in hot weather, allowing both leaves and flowers to droop, sometimes to an alarming degree, Wilting occurs when the pace at which plant leaves dispel moisture into the air is greater than the amount of water absorbed by the leaves , that is transpiration , outplays the supply of water by the roots. Hence, some plants wilt even when plenty of water is available during the day and recover in the evening
