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 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-3: -Sufficient water is essential for plant growth and production. Root hairs connect roots to the soil, extend the effective root radius, and greatly enlarge the absorbing surface area.
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.
Detailed explanation-5: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.
