The upward movement of water and dissolved mineral salts from roots upwards to the leaves and other aerial parts is called Ascent of Sap. (It is called the sap as it contains many dissolved minerals). This water is conducted upwards to the leaves through xylem. Ascent of sap involves root pressure and transpiration pull.
