Answer:
There are three types of meristematic tissues: apical (at the tips), intercalary (in the middle), and lateral (at the sides).
Explanation:
Types of Meristematic Tissue
The meristematic tissue is of the following types:
Meristematic Tissue On the basis of Origin
Promeristem
The earliest and youngest meristematic tissue.
It originates from the embryo.
The primary meristem arises from the promeristem.
It is found in the root and the shoot tips.
Primary Meristem
It arises from the promeristem.
Cells divide actively.
It is present below the promeristem and forms the permanent tissue.
Secondary Meristem
It originates from the primary meristem.
The permanent tissue forms from the secondary meristem.
Meristematic Tissue On the Basis of Position

Meristematic Tissue – Based on Occurrence
Apical Meristem
These are present at the tips of the roots and shoots and helps in the increase of the height of the plants.
Various cell divisions facilitate the growth of the cells in the roots and shoots and help in cellular enlargement.
Apical meristem is divided into-promeristem zone, which contains actively dividing cells, and the meristematic zone, which contains protoderm, procambium and ground meristem.
Intercalary Meristem
It is located in the leaves and internodes at the intercalary position.
These help to increase the length of the internode.
It is found in grass, monocots and pines.
It is a part of apical meristem and adds to the height of the plant.
Lateral Meristem
It is located in the stems and roots on the lateral side.
It increases the thickness of the plant.
Vascular cambium and cork cambium are the two lateral meristems.
These divide preclinically or radially and give rise to secondary permanent tissues.
