The growth of plants occurs only in certain specific regions. This is because the dividing tissue also known as meristematic tissue is the region where they are present, meristematic tissues are classified as apical, lateral and intercalary.
Apical meristem is present at the apical or growing tips of stems and roots. Apical meristem increases the length of the plant.
Lateral meristem is present in the radial portion of the stem or root. Lateral meristem increases the girth of the plant.
Intercalary meristem occurs at the base of the leaves or at the internodes. Intercalary meristem increases the length of the internode.
