HORTICULTURE

Detailed explanation-1: -The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure 23.16). The zone of cell division is closest to the root tip; it is made up of the actively dividing cells of the root meristem.

Detailed explanation-2: -Regions of root from base to root tip are-Maturation zone – Elongation zone – Cell division zone. Hence the correct answer is option ‘B’.

Detailed explanation-3: -The region of cell division is found just under the root cap. In this region, cells are perpetually dividing (mitosis), meaning there is a constant generation of new cells, causing the root to grow in length (primary growth).

Detailed explanation-4: -So, the correct answer is ‘Maturation zone-Elongation zone-Cell division zone’
