"WebThe endosmosis of water continues until the water potential both in the root and soil becomes equal. It is the absorption of minerals that utilise metabolic energy, but not water absorption. Hence, the absorption of water is indirectly an active process in a plant's life. Active transport is in an opposite direction to that of diffusion. " - Peg water absorption
