Vedclass · Answer

(D) Water absorption by root hairs occurs via the process of osmosis. For water to move from the soil (external medium) into the root hair cells,the water potential inside the root hair cells must be lower than that of the soil. This means the soil solution must be a $Hypotonic$ solution relative to the cell sap of the root hair. In a $Hypotonic$ solution,the concentration of solutes is lower,and the water potential is higher,allowing water to move into the cell through the semi-permeable membrane.
