B)store starches.
C)increase the surface area for absorption.
D)provide a habitat for nitrogen-fixing bacteria.
E)contain xylem tissue.

Accepted Answer

Root hairs are thin, hair-like extensions of the epidermal cells on the roots of plants. They greatly increase the surface area of the root and thus increase the area available for absorption of water and nutrients from the soil. This makes them important for the plant's ability to take up essential elements needed for growth and survival.
