A root hair cell is a typical plant cell in that it has a cell wall and a large vacuole, but it has a special shape to increase its surface area making it very effective at absorbing water. It doesn’t have chloroplasts because it is underground where there is no light.

The root hairs emerge from the root to increase its surface area.

The roots branch out to find water and anchor the plant securely to the ground.
