Vedclass · Answer

(A) Passive guttation occurs when the rate of water absorption is very high and the rate of transpiration is very low. This process is driven by the $Tension-cohesion$ force of water molecules,which pulls water through the xylem to the hydathodes. Unlike active guttation,which involves the metabolic activity of the $Epithem$ tissue,passive guttation is a physical process resulting from the water potential gradient created by high transpiration pull or high root pressure under conditions of low evaporation.

List-$I$	List-$II$
$(a)$ Cohesion	$(i)$ More attraction in liquid phase
$(b)$ Adhesion	$(ii)$ Mutual attraction between water molecules
$(c)$ Surface tension	$(iii)$ Water loss in liquid phase
$(d)$ Guttation	$(iv)$ Attraction towards polar surfaces

Which of the following is responsible for passive guttation?
