root cap

…producing the cells of the root cap. The cells derived from the other faces continue to divide mostly by forming transverse walls, but occasionally also in the longitudinal plane. In this way vertical columns of cells form—tending, because of their mode of origin, to be disposed in three sectors.

…is covered by a thimble-shaped root cap, which serves to protect the growing tip as it makes its way through the soil. Just behind the root cap lies the apical meristem, a tissue of actively dividing cells. Some of the cells produced by the apical meristem are added to the…

…living parenchyma cells called the root cap. As the cells of the root cap are destroyed and sloughed off, new parenchyma cells are added by a special internal layer of meristematic cells called the calyptrogen. Root hairs also begin to develop as simple extensions of protodermal cells near the root…

…of loose cells called the root cap. Just beneath the root cap is the region of cell division of the root. Epidermal outgrowths just above the root tip are root hairs that are active in water and mineral absorption. Two types of root systems are commonly distinguished, fibrous roots and…
