WebThe active absorption depends on the active accumulation of solute in xylem sap. 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. WebRoot pressure is the pressure in roots caused by the osmosis between roots and soil. It is also called as osmotic pressure. The manometer is a device used for measuring root pressure. Whereas potometer is used to measure the rate of transpiration, a barometer is used to measure atmospheric pressure and auxanometer measures the rate of growth of ...
