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: -The movement of water is due to the difference in the osmotic pressure. The osmotic pressure of water in roots is high and so the water enters the root hair cells. The water is transported to the other cells in the root region by osmosis.
Detailed explanation-3: -The process by which water enters the root hair cell is called as osmosis. Due to the semipermeability and low potential of water, water enters into root hair through osmosis.
