List the meristems in various parts of the plant and list their functions.

Meristematic tissues are found at all growing points of a plant like tips of roots, stems, branches. These cells can multiply rapidly to produce new cells. According to their position in plant, they are apical, lateral and intercalary meristem.

Apical meristem- They are situated at the growing tip of stems and roots and apices of young leaves, tips of auxillary buds. They help to increase the length of roots and stem.

Lateral meristem- They are found below bark, cambium, in dicot roots and stems. They increase the diameter of the stem.

Intercalary meristem- They are found at the base of leaves or internode like stems of grasses and other monocots. They help in increasing the length of the stem.
