Answer
The three special features of root hairs which make then suitable for the absorption of water from the soil are:
- The numerous root hairs provide a large surface area. More the surface area, greater is the absorption.
- Root hairs contain cell sap which is of a higher concentration than the surrounding soil water.
- The cell wall is freely permeable, i.e., permits movements of all types of substances. But the cell membrane is semi-permeable. It allows only some substances to pass through it.
