Vedclass · Answer

(D) Root pressure is a positive hydrostatic pressure that develops in the xylem of roots due to the active absorption of mineral ions. It is responsible for phenomena like sap exudation,bleeding,and guttation. Transpiration,on the other hand,is the loss of water in the form of vapor from aerial parts of plants. It is driven by the cohesion-tension-transpiration pull mechanism,which is a negative pressure (suction) mechanism,not a positive pressure mechanism like root pressure.

Which of the following phenomena is not associated with root pressure?
