Cells in meristematic tissue are highly active, characterized by dense cytoplasm, thin cellulose walls, prominent nuclei, and a lack of vacuoles.

Intercalary meristem is located near the nodes in some plants and contributes to the elongation of stems and roots at specific points, allowing for continued growth and development.

Lateral meristem, also known as cambium, is responsible for increasing the girth or diameter of the stem or root by producing new cells that add to the secondary growth of the plant.

Apical meristem is located at the growing tips of stems and roots and is responsible for increasing the length of the stem and the root by producing new cells through cell division.

Meristematic tissues are classified as apical, lateral, and intercalary depending on where they are present in the plant.
