The root tip, the growing end of a plant root, is a complex structure composed of several zones that facilitate its growth and function. It is covered by a root cap, a protective layer of cells that shield the delicate meristematic tissue beneath as the root pushes through the soil. Behind the root cap lies the apical meristem, a region of actively dividing cells responsible for primary growth (increasing root length). Further back are the zone of elongation, where cells increase in size, and th
