Answer 1

The correct option is B C, B, E, A, D

Following zones as seen in the root in vertical section:

● Root cap zone

● Zone of meristems

● Zone of elongation

● Root hair zone

● Zone of maturation


Root cap zone:

Root cap zone is a cap-like structure made up of parenchymatous cells which protects the root apex.

Zone of meristems:

Zone of meristems is situated behind the root cap and is a small region made up of meristematic cells (small thin-walled cells with dense protoplasm) which is responsible for active cell division and growth.

Zone of elongation:

Zone of elongation is situated behind the zone of the meristem where the cells rapidly elongate and enlarge. This contributes to the increase in length of the roots.

Root hair zone:

Root hair zone is situated proximal to the zone of elongation, and root hair (thin, thread-like structures) are present for the absorption of water and minerals from the soil.

Zone of maturation:

Zone of maturation is situated behind the zone of elongation and made up of mature cells which do not grow further. It provides mechanical support to the plant.

Final answer:

a. C, B, E, A, D
