Vedclass · Answer

(B) Exudation (bleeding) of xylem sap occurs when a plant is cut or injured. This phenomenon is primarily caused by $Root \ pressure$. Root pressure is a positive pressure that develops in the xylem sap of roots due to the active absorption of mineral ions from the soil,which leads to water following by osmosis. This pressure is sufficient to push water and solutes up to small heights in the stem,resulting in exudation.
