Dixon and Jolly's Cohesion-Tension and Transpiration Pull Theory

Vedclass · Answer

(D) The most widely accepted theory for the ascent of sap in plants is the $Dixon$ and $Jolly's$ $Cohesion-Tension$ and $Transpiration$ $Pull$ $Theory$. According to this theory,the transpiration pull generated in the leaves creates a negative pressure (tension) in the xylem vessels. Due to the cohesive and adhesive properties of water molecules,a continuous water column is maintained from the roots to the leaves. This tension pulls the water column upward against gravity,facilitating the ascent of sap.
