Detailed explanation-1: -Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration in order to provide the energy needed for active transport.

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: -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: -They are long and thin so they can penetrate between soil particles and they have a large surface area for absorption of water.
