(a) Transpiration pull and cohesion-tension theory of ascent of sap was proposed by Dixon and Jolly (1894). The molecules of water show cohesion and molecule of water and vessel wall show adhesion. Due to these forces water column does not break and pulled upward by the force called transpiration pull. The transpiration pull is developed due to transpiration. |
