Question

compare the three types of meristems.

Answer 1

Heya !

The Three types of meristem are :-

• Apical meristems => These are situated at the growing tip of stems and roots i,e at shoot apex and root apex. Apical meristems are also found at apices of the leaves.

• Lateral meristems => These are found beneath the bark called cork cambium and occur in vascular bundles of dicot roots and stems called vascular cambium. They occur in thin layers. Cambium is the region which is responsible for growth in thickness.

• Intercalary meristems => They are located at the base of leaves or internode ,eg., stems of grasses and other monocots. Such tissues also occur below the nodes ( e.g., mint ).


Hope it helps !!!

Answer 2

There are total 3 types of meristems, they are :-

1. Apical meristem ⇒ These are situated at the growing tip of stem and roots, i.e., at shoot apex & root apex respectively.

It is responsible for the growth or elongation of the root and stem, & it is called primary growth.

2. Lateral meristem ⇒ These are found beneath the bark (called cork cambium) and in vascular bundle of dicot roots and stems (called vascular bundle).

It is responsible for increase in girth, This is called secondary growth.

3. Intercalary meristems ⇒ They are located at the base of leaves or internodes.

It is responsible for the increase in the length of a leaves and internodes.
