Plant Tissue: Meristems

Question

Intercalary meristems in grasses contribute primarily to which growth?

RankGuru · Accepted Answer

1. **Meristems**: Regions of active cell division in plants.
2. **Intercalary Meristems**: These are derived from apical meristems but are separated from the tip by permanent tissues.
3. **Location**: Common in grasses, found at the base of leaves or **internodes**.
4. **Function**: They are responsible for the **elongation of the internodes** and help the plant recover (regrow) parts removed by grazing herbivores.
5. **Note**: Lateral meristems ($e.g.,$ vascular cambium) are responsible for the increase in girth (secondary growth).
