Detailed explanation-1: -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-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 structures which increase the surface area of absorption of water and minerals.

Detailed explanation-4: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.

Detailed explanation-5: -Root hair cells are specialized epidermal cells that greatly increase the surface area of roots. As such, they are widely believed to play an important role in plant nutrition by facilitating the absorption of water and nutrients.
