Detailed explanation-1: -Explanation: 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: -Most of the water that a plant takes in enters through the root hairs. The water diffuses easily (and osmotically) into the root hairs because the concentration of dissolved materials in the plant’s cellular cytoplasm is high.

Detailed explanation-3: -Water enters the root hair cells by osmosis. This happens because soil water has a higher water potential than the cytoplasm of the root hair cell. Minerals enter by active transport .

Detailed explanation-4: -Water enters the root hair cells by osmosis . This happens because soil water has a higher water concentration than the cytoplasm of the root hair cell.

Detailed explanation-5: -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.
