Question

List the characteristics of root hair that make it suitable for absorbing water?

Answer 1

1. The majority of water absorption occurs in the root hairs. Because they are long, they can penetrate between soil particles and keep harmful bacterial organisms from entering the plant via the xylem vessels. They have a large surface area for water absorption.
2. Surface area of roots is enormous.
3. Root hair contains more cell sap than the surrounding water, allowing water to move through it via osmosis.
4. Root hair has thin cell walls and cell membranes that allow water molecules and dissolved substances to move into and out of the cell.
