Numbers and Quadratic Equations, Introduction This is called transpiration pull or tension in the water column of xylem due to transpiration. Transpiration Pull Theory in plant water transport. This theory is based on two parts (i) Transpiration pull exerted on the water column. ! Transpiration pull • How water achieves the height of 15meters per hour? b) Continuity of water column in the plant. Mutual attraction between water molecules is called cohesion and this force may have a value as high as 350 atmospheres. Today most of the workers believe in this theory. iv) Cohesion and Adhesion Theory or Transpiration Pull Theory: This theory was given by Dixon & Jolly (1894) and Askenasy (1895). 1. Dixon and Jolly gave transpiration pull theory for ascent of sap. The main features of the theory are: According to this theory, ascent of sap in plants is a passive physical process, which occurs under the influence of transpiration pull generated due to loss of water from aerial parts.

Answer: Transpiration pull – cohesion tension theory; Dixon & Jolly; Question 9. This is called 'transpiration pull'. to Three Dimensional Geometry, Application solution of water and mineral ions absorbed from soil which moves upward from root to various parts of plants the theory states that transportation pull or tension cohesion ... the various theories to explain ascent of sap are transpiration pull and cohesion theory cohesion tension theory the theory was originally proposed by dixon and jolly 1894 The transpiration taking place through leaves causes negative pressure or tension in xylem sap which is transmitted to the root. Cohesion-tension or Cohesion & adhesion Theory or Transpiration pull theory (Dixon’s and Jolly Theory, 1894). This is presently a widely accepted theory explaining the ascent of sap in plants. Algebraic This is also called as cohesion-tension theory put forward by Dixon and Joly (1894) and supported by Renner, Curtis andClark.This theory is based on a number of features.. Cohesion and Adhesion . Dixon and John Jolly observed that transpiration, osmotic uptake of water by living cells, and hydration of cell walls (adhesion) create tension. Dixon and John Jolly observed that transpiration, osmotic uptake of water by living cells, and hydration of cell walls (adhesion) create tension. Cohesion and Adhesion :

D. Cohesion tension theory: Cohesion-tension or Cohesion & adhesion Theory or Transpiration pull theory (Dixon’s and Jolly Theory, 1894). Transpiration Pull and Cohesive Force Theory: This theory was proposed by Dixon and Jolly (1894) and at present, it is the most accepted principle for explaining the ascent of sap.
