answered-by-expert Expert Answer
It is due to the absorption of water and nutrients from the soil by the roots. The root hairs 
 
1. The root hairs cover a large surface area. More the surface area, the greater is the absorption.
2. The cell membrane is semi-permeable.
3. The vacuoles present in the root hair cells contain cell sap. The water concentration in cell sap is lower than the concentration of water in the soil.
