Explanation:
Detailed explanation-1: -Root hairs form in the zone of differentiation and this is where they begin to poke out into the soil to absorb water and mineral nutrients. Root hairs greatly increase the root surface area and therefore increase the ability of a plant to absorb water and nutrients.
Detailed explanation-2: -In the elongation zone, cells elongate rapidly and undergo a final round of divisions to develop a central ring of cells known as endodermis. Endodermis gives rise to two regions-the cortex toward the outside and the stele towards the inside.
