Detailed explanation-1: -Root hairs develop from the region of maturation. Certain epidermal cells from this region form fine and delicate, thread-like structures called root hairs which help in the absorption of water and minerals.
Detailed explanation-2: -Root hairs usually arise as protrusions from the external, lateral walls of epidermal cells, although in a few species they originate from cortical cells one or two layers beneath the epidermis.
Detailed explanation-3: -ZONE OF MATURATION (= ZONE OF CELL DIFFERENTIATION): The vascular tissues of the root become differentiated. Instead of forming bundles containing xylem and phloem, as in leaves and young shoots, the xylem forms a solid mass in the center, surrounded by strands of phloem.
Detailed explanation-4: -Root hairs grow in the zone of maturation, and this is where they begin to push out into the soil to gather water and mineral nutrients. Root hairs considerably enhance the root biomass and boost a plant’s capacity to absorb more water and nutrients.
