Vedclass · Answer

(C) The process of guttation involves the exudation of liquid water from the tips or margins of leaves through specialized structures called hydathodes.This phenomenon occurs due to the development of a positive hydrostatic pressure,known as $root \ pressure$,in the xylem vessels at the vein endings.This $root \ pressure$ forces the liquid water out through the hydathodes,especially when transpiration is low and water absorption is high.
