Vedclass · Answer

(B) Water absorption by root hairs occurs primarily through the process of osmosis. Osmosis is the movement of water molecules from a region of higher water potential (lower solute concentration) to a region of lower water potential (higher solute concentration) through a semi-permeable membrane. When the concentration of solutes in the root hair cell sap is high,the water potential inside the cell becomes lower than that of the surrounding soil water. Consequently,water moves from the soil into the root hair cells to balance the concentration gradient. Therefore,option $B$ is the correct answer.
