Apical meristems are located at shoot and root tips and are responsible for primary growth (increase in length). Intercalary meristems are found at the base of nodes and leaves, also contributing to primary growth in certain plants (like grasses). Lateral meristems (vascular and cork cambium) are responsible for secondary growth (increase in thickness).
