State the different types of meristematic tissues and also state their functions
Answers
Answer:
There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
Apical Meristem
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.
Apical Meristem
These are present at the tips of the roots and shoots and helps in the increase of the height of the plants.

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
