Most accepted theory for ascent of sap is

Step-by-step solution

Transpiration pull is the tension which develops due to transpiration. It has been demonstrated and evidenced, that rate of water absorption and hence, ascent of sap closely follows the rate of transpiration and hence, ascent of sap closely follows the rate of transpiration. Cohesion and transpiration pull theory, given by Dixon and Jolly (1894) is the most accepted theory for ascent of sap. Root Pressure theory (Priestley; 1916) is a manifestation of active water absorption. It was objected, as it has not been app
