Detailed explanation-1: -Root hairs are the lateral epidermal extensions or tubular outgrowths in the roots (zone of maturation) of plants. The root hairs penetrate into the soil and prevent harmful microbes from entering the plant through the xylem vessels. They increase the surface area for absorption of water and nutrients from the soil. More items
Detailed explanation-2: -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-3: -Roots have numerous root hairs that increase the surface area for the absorption of water and minerals. These root hairs are in contact with the water present in the soil. Water enters the cells of the root hair by the process of osmosis.
