Step-by-step solution
The root apex consists of different zones with specific characteristics. The root cap (A) is a thimble-like structure that protects the tender apex of the root (IV). The region of meristematic activity (B) is located a few millimetres above the root cap. Its cells are very small, thin-walled, and with dense protoplasm (I). The region of elongation (C) is proximal to the meristematic region, where cells undergo rapid elongation and enlargement (II). The region of maturation (D) is proximal to the elongation zone, wh
