Hint: Regions of roots – A root is a part of the plant that develops underground and helps the plant firmly in the soil. Roots are homogeneous in nature as they produce similar organs from the pericycle.
Regions of root from base to root tip are as follows-
Zone of maturation – The base of the root is defined as the maturation zone. Maturation zone contains the vascular cylinder and root hair. In this region, functional cells are found.
Zone of cell elongation – In this zone cellular expansion is responsible for pushing the root cap and apical tip forward through the soil.
Zone of cell division - This zone gives rise to the primary body of the plant. It is the area under and behind the root cap.
A) Maturation zone – Cell division zone – Elongation zone: is an incorrect Option
B) Maturation zone – Elongation zone – Cell division zone: is the correct answer because regions of root from base to tips are in this sequence. Thus, this is the correct answer.
C) Cell division zone - Elongation zone - Maturation zone: is an incorrect answer
D) Elongation zone - Cell division zone - Maturation zone: is an incorrect answer.
Regions of root from base to root tip are-Maturation zone – Elongation zone – Cell division zone.
Hence the correct answer is option ‘B’.
Note: The zones of the root are the area of soil and nutrients surrounding the root. The zones help in absorbing water and nutrients from the soil. Roots are the region where the vascular system that is the xylem and the phloem begins.
