Answer:

The more root hairs a plant has, the larger will be surface area to increase the rate of absorption.

Explanation:

The role of root hairs of a plant is to collect mineral nutrients and water available in the soil and absorb the solution up through the roots.

Water enters through the root hair cells and moves from one cell to another till it reaches the root cortex. Water goes on to the xylem vessels to be carried to the leaves

The plant absorbs more water and nutrients by growing root hairs on the tips of their roots to increase the surface area underground.
