Vedclass · Answer

(D) - In a dry atmosphere,the relative humidity is low,which increases the water potential gradient between the leaf interior and the atmosphere,thereby increasing the rate of transpiration.- $A$ slow breeze removes the humid air surrounding the leaf surface,replacing it with drier air,which promotes the rate of transpiration.- $ABA$ (Abscisic acid) inhibits transpiration by inducing stomatal closure; therefore,it is known as a stress hormone.- $A$ high salt concentration in soil water lowers the water potential of the soil,making it difficult for plants to absorb water,which decreases the rate of transpiration.

$A.$ In dry atmosphere,the relative humidity is low,so the rate of transpiration increases.
$B.$ Slow breeze promotes the rate of transpiration.
$C.$ $ABA$ promotes transpiration.
$D.$ $A$ high salt concentration in soil water increases transpiration.
