why do leaves w i l t during the afternoon in bright sunlight what is needed to revive them

Answer 1

hello brother your answer is here..

Prolonged hot sun and dry soil are the primary, but not the only, causes of wilting. Leaves are likely to droop more when air is dry as well as hot. High humidity on a hot summer day can reduce the quantity of water from roots needed by leaves. Wind can increase water needs and cause more drooping.

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, in a process called transpiration, outpaces the ability of plant roots to supply enough water.

The concentration of water molecules inside the cell is higher than the concentration of water outside. Describe what happens to a wilted plant when it is watered. When a wilted plant is watered, osomosis makes the plant firm again.
