Rearrange the following zones as seen in the root in vertical section and choose the correct option.

A. Root hair zone

B. Zone of meristems

C. Rootcap zone

D. Zone of maturation

E. Zone of elongation

Options:

C, B, E, A, D

Explanation:

Root cap zone – The root is covered at the apex by a thimble-like structure called the root cap.

Zone of Meristem – It is a region just above the root cap. The cells of this region are very small, thin-walled and with dense protoplasm. They divide repeatedly.

Zone of elongation – The cells of this region undergo rapid elongation and enlargement and are responsible for the growth of the root in length. This region is called the region of elongation.

Zone of maturation – The cells from the zone of elongation when differentiate and mature gradually, they enter the zone of maturation.

Root hair zone – From zone of maturation, some of the epidermal cells form very fine and delicate, thread-like structures called root hairs.
