Consist of actively-dividing cells. Meristematic Tissues are of three types:
- Apical meristem
- Intercalary meristem:
- Lateral meristem
Present at the growing tips of stems and roots. Important function: To increase the length of stems and roots.
Present at the base of leaves or internodes. Important function: For the longitudinal growth of plants.
Present on the lateral sides of the stems and roots. Important function: To increase the thickness of stems and roots.
Formed from meristematic Tissues, the cells in the tissue loose the ability to divider Permanent Tissues are divided into two categories:
