(D) The upward movement of water and dissolved minerals (sap) through the xylem against the force of gravity is known as the ascent of sap.Root pressure provides a positive push to the water column.Transpiration creates a negative pressure (transpiration pull) that pulls water upwards.Capillarity (capillary action) due to the narrow diameter of xylem vessels also assists in the movement of water.Therefore,all these factors contribute to the ascent of sap.
