Root hairs are produced in which region?

Explanation:
Root hairs form when epidermal cells differentiate in the region behind the elongation zone—the Region of Maturation. In this zone, cells stop dividing and elongating and acquire specialized functions. Epidermal cells become trichoblasts and extend outgrowths that become root hairs, greatly increasing the surface area for water and mineral uptake. The meristematic zone is where cells are actively dividing, so root hairs don’t form there, and the elongation zone is where cells lengthen before differentiation. (Differentiation and maturation refer to the same phase where cells become specialized, including the formation of root hairs.)
