Vedclass · Answer

(C) Root pressure is defined as a positive pressure that develops in the xylem sap of roots as a result of metabolic activities. It is considered an active process because it requires the expenditure of energy to actively transport mineral ions from the soil into the root hairs. This accumulation of ions decreases the water potential inside the root,causing water to enter the root cells from the soil via osmosis. Therefore,the development of root pressure is a consequence of active transport followed by osmosis.
