NEET BIOLOGY

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 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.

Detailed explanation-3: -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-4: -The root hair increases the surface area of the root for the absorption of water and mineral nutrients dissolved in water.
