While examining a longitudinal section of a root tip, a biologist observes a specific zone where the cells are very small, thin-walled, and contain dense protoplasm. Identify this region of the root.

Step-by-step solution

The root apex is covered by a thimble-like structure called the root cap. A few millimetres above the root cap lies the region of meristematic activity. The cells in the region of meristematic activity are very small, thin-walled, and contain dense protoplasm. These cells divide repeatedly to produce new cells for root growth. The cells proximal to this region undergo rapid elongation and enlargement, forming the region of elongation. Further proximal to the region of elongation is the region of maturation, where c
