Question

What is the benefit of root hairs on the root of a plant?

Answer 1

Root hairs present on the root of the plant help in increased absorption of water from the soil.

Explanation:

Roots are the organ to absorb water from the soil. The capillary water in the soil is available to the root for absorption.

The terminal part of the growing root absorbs water from the soil. Most of the water is absorbed through root hair zone . The root hairs are extensions of epidermal cells of the root.

Root hairs increase the surface area for absorption of water. Thus these are beneficial to root for effecting absorption more efficiently.
