WebDec 20, 2024 · When a pressure greater than the atmospheric pressure is applied to pure water the water potential increases. It leads to positive root pressure as when water diffuses into a plant cell, a pressure is built up against the cell wall which swells the cell wall. Ques. Give the reason why pure water has the maximum water potential. (3 Marks) WebDec 21, 2024 · 81 Root pressure is often measured in excised roots by stopping the exudation of xylem sap from 82 roots and measuring the maximum pressure (Steudle and Peterson, 1998; Henzler et al., 1999). 83 The osmotic effects acting on a semi-permeable ‘membrane’ are implicated in the generation of 84 root pressure. In living cells, this …

Root pressure in maximum when transpiration is very low and absorption is high because transpiration is the output of water from a plant, and absorption is the input of water into a plant. If the output is low and input is high, the pressure will be at its greatest. horizon shenango valley
