Detailed explanation-1: -Root hair are fine hair-like outgrowths of root epidermal cells which increase the surface area for the absorption of water and exchange of gases.

Detailed explanation-2: -Root hairs. Single celled and large surface area, perfect for absorption of water and nutrients! Root hairs are long, thin, single cell extensions from the epidermis. They profoundly increase the overall root surface area and connection with the soil and are responsible for absorbing water and mineral nutrients.

Detailed explanation-3: -The root hairs on roots increase the surface area of roots to facilitate absorption of water and minerals that are dissolved in the soil water. The xylem then conducts the absorbed water and minerals from the roots to the shoot system.

Detailed explanation-4: -Root hairs are long tubular-shaped outgrowths from root epidermal cells. In Arabidopsis, root hairs are approximately 10 µm in diameter and can grow to be 1 mm or more in length (Figure 1).

Detailed explanation-5: -Root hair is an elongated tubular extension of an epidermal cell of a root. Root hair is unicellular, with a very thin cell wall and devoid of cuticles. This allows free movement of substances in and out of the root hair cell.
