Answer to Question #73011 in Biology for Bushra Nasim

Question

Why does witling of leaves takes place in hot summer days? Reason

Answer 1

During hot summer days, water loss by means of transpiration increases, while the supply of water for the roots does not change. As a result, leaf cells lose water faster than they gain it from xylem vessels. If such negative water balance is maintained for long, the plant wilts.
