Vedclass · Answer

(C) The Transpiration pull and cohesion-tension theory was proposed by Dixon and Jolly $(1894)$.The water molecules form a continuous column within the xylem due to cohesion (attraction between water molecules).The cell walls of xylem vessels have a strong affinity for water molecules,which is known as adhesion.Loss of water from aerial parts through transpiration creates a negative pressure or tension in the water column of the plant,which is called suction pull or transpiration pull,allowing the column to extend upward.

In tall plants,because of which factor,does a continuous water column extend upward?
