Meristematic tissue:

meristematic tissues are the tissues present on the tip, sides and in between layers of other tissues.

Meristematic tissues at the growing tip that bring about growth in length are called as apical meristematic tissues.

Tissues present around the edges in a lateral manner and giving rise to growth in girth of the stem are called lateral meristematic tissues.

Areas from which branching takes place or a leaf or a flower stalk grows this kind of meristematic tissue called as intercalary meristematic (also called as Cambium) tissue.
