Vedclass · Answer

(A) Water absorption by root hairs occurs primarily through the process of osmosis. Osmosis is the movement of water from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution) across a semi-permeable membrane. When the concentration of solutes (minerals/salts) in the cell sap of the root hair increases,the water potential inside the cell decreases. This creates a gradient that allows water to move from the soil into the root hair cells.
