Vedclass · Answer

(D) The theory of ascent of sap,proposed by Dixon and Jolly,is known as the Cohesion-Tension-Transpiration Pull theory.This theory explains that water moves upward in plants due to the transpiration pull generated in the leaves,which is transmitted down to the roots through a continuous water column.The integrity of this water column is maintained by the cohesive forces (attraction between water molecules) and adhesive forces (attraction between water molecules and the walls of tracheary elements).The theory states that this process is passive and does not require metabolic energy in the form of $ATP$.Therefore,the requirement of $ATP$ is against the principles of this theory.
