Question

13) Water moves from the roots to the leaves because of: A) positive root pressure from differences in solute potential between soil and root. B) positive pressure generated by the shrinking in diameter of the trunk or stem. C) adhesion of water molecules to xylem cell walls. D) pressure differential created by proton pumping of stomatal guard cells. E) negative pressure at the air-water interface in the leaf.
