What is the location of intercalary meristem in plants?
Intercalary meristem is a type of meristematic tissue found at the base of leaves and internodes in plants, particularly monocots like grasses. It is responsible for growth in length in the internodal regions, allowing parts that have already differentiated to elongate.
Apical meristems are found at shoot and root tips (C and parts of B), responsible for primary growth (increase in length). Lateral meristems (vascular cambium, cork cambium) are found in stems and roots (B), responsible for secondary growth (increase in girth). Intercalary meristems are located between mature tissues, enabling growth in regions away from the apical meristem.
The presence of intercalary meristems allows grasses to regrow quickly after being grazed or mowed, as growth can occur from the base of the leaves and stems rather than just from the tips.
