- The shoot apical meristem is terminal in position, whereas the root apical meristem is subterminal, meaning it is located behind the root cap.
- Intercalary meristem:
- The top or base area of the node contains intercalary meristematic tissue.
- Their activity is mainly seen in monocots.
- These are short-lived.
