Which of the following physical forces is supposed to be responsible for the ascent of sap ? A number of vital force theories have been proposed by different scientist. MANY theories have been formed to account for the ascent of sap in high trees, when root pressure is not acting. The translocation of water through the length of a plant takes place primarily in the xylem portion of the vascular tissue system. distinct factors or forces which are responsible for ascent of sap in plants are the root pressure, transpiration pull and capillarity. The 'Saugkraft' of the leaf, or its suction force, has been appealed to by many. Revised April 20, 1895. The upward movement of water and minerals dissolved in it from the roots to the top of the plants was termed as the ascent of sap. •Theory of capillary force responsible for ascent of sap was given by Boehm in 1809.
