Detailed explanation-1: -Osmosis is the process by which the molecules of a solvent, such as water, move from a region of its higher concentration to a region of its lower concentration through a semipermeable membrane. Explanation: Water enters the root hairs by the process of osmosis.
Detailed explanation-2: -Water moves into the roots from the soil by osmosis, due to the low solute potential in the roots (lower s in roots than in soil). This intake o f water in the roots increases p in the root xylem, driving water up.
Detailed explanation-3: -The root hairs take water from the soil by a process called osmosis. In osmosis, water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
Detailed explanation-4: -Osmosis: The process by which water enters the root hair cell is known as osmosis. Water enters root hair through osmosis due to the semipermeability and low potential of water.
