SSC MTS EXAM

Detailed explanation-1: -In osmosis, water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. The concentration of the water molecules is lower in the root hair than in the soil. So the water moves into the root hairs through osmosis.

Detailed explanation-2: -Water enters root hair cells by osmosis. The root hair cell is hypertonic to the surrounding soil water. Water then moves from cell to cell through the root cortex by osmosis along a concentration gradient; this means that each cell is hypertonic to the one before it. More items
