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: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.
Detailed explanation-3: -Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient.
Detailed explanation-4: -The main function of root hairs is the uptake of water and nutrients from the rhizosphere.
Detailed explanation-5: -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).
