Detailed explanation-1: -Root hairs enhance the surface area available for the absorption of water and minerals. These root hairs come into contact with the soil’s water. Osmosis allows water to enter the cells of the root hair.

Detailed explanation-2: -The correct option is A root hair. Root hair are fine hair-like outgrowths of root epidermal cells which increase the surface area for the absorption of water and exchange of gases.

Detailed explanation-3: -Root hair, or absorbent hairs, are outgrowths of epidermal cells, specialized cells at the tip of a plant root. They are lateral extensions of a single cell and are only rarely branched.

Detailed explanation-4: -Root hairs. Single celled and large surface area, perfect for absorption of water and nutrients! Root hairs are long, thin, single cell extensions from the epidermis. They profoundly increase the overall root surface area and connection with the soil and are responsible for absorbing water and mineral nutrients.

Detailed explanation-5: -Root hairs are thin-walled slender extensions of root epidermal cells, that greatly increase the surface area for absorption. Water is absorbed along with mineral solutes, by the root hairs, purely by diffusion.
