Vedclass · Answer

(D) The ascent of sap is the upward movement of water and minerals from the roots to the aerial parts of the plant. $1$. Root pressure provides a positive pressure that helps in pushing water upwards to small heights. $2$. Transpiration creates a negative pressure (transpiration pull) which is the primary force for the ascent of sap in tall plants. $3$. Capillarity (capillary action) due to the narrow diameter of xylem vessels also contributes to the upward movement of water. Therefore,all these factors contribute to the ascent of sap.
