Root hair cells black arrow pointing at one of the root hair cells are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant`s root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere. Structure function illustrations
