Detailed explanation-1: -The length of root hairs allows them to penetrate between soil particles and prevents harmful bacterial organisms from entering the plant through the xylem vessels. Increasing the surface area of these hairs makes plants more efficient in absorbing nutrients and interacting with microbes.
Detailed explanation-2: -Because they vastly increase the root surface area and effectively increase the root diameter, root hairs are generally thought to aid plants in nutrient acquisition, anchorage, and microbe interactions (Cutter, 1978; Hofer, 1991).
Detailed explanation-3: -Root hairs are the small tubular extensions of the root surface which help in the absorption of water and minerals from the soil. It increases the surface area for absorption. More number of root hairs will increase the surface area and increase water absorption also.
Detailed explanation-4: -Figure 2: Root hairs often form on fine roots and improve water absorption by increasing root surface area and by improving contact with the soil.
