Detailed explanation-1: -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-2: -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-3: -Roots hairs are cylindrical extensions of root epidermal cells that are important for acquisition of nutrients, microbe interactions, and plant anchorage.

Detailed explanation-4: -Root hair is an elongated tubular extension of an epidermal cell of a root. Root hair is unicellular, with a very thin cell wall and devoid of cuticles. This allows free movement of substances in and out of the root hair cell.

Detailed explanation-5: -The root hairs take water from the soil by a process called osmosis. In osmosis, water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
