NEET BIOLOGY

Detailed explanation-1: -Water enters the root hairs by the process of osmosis. 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.

Detailed explanation-2: -Therefore, the amount of water is much higher in the soil than inside of the cell, allowing the water to enter the root hair cell through the process of osmosis.

Detailed explanation-3: -Water entered through the root of the plant is transported to leaves and is lost in the air. The hair of the root is hypertonic to the surrounding soil or water. This causes the entry of water from the soil to the root hair through the process of osmosis.

Detailed explanation-4: -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. The concentration of the water molecules is lower in the root hair than in the soil.
