Solution
Correct Answer:
Elongation of internodes
- Meristems: Regions of active cell division in plants.
- Intercalary Meristems: These are derived from apical meristems but are separated from the tip by permanent tissues.
- Location: Common in grasses, found at the base of leaves or internodes.
- Function: They are responsible for the elongation of the internodes and help the plant recover (regrow) parts removed by grazing herbivores.
- Note: Lateral meristems (e.g., vascular cambium) are responsible for the increase in girth (secondary growth).
This easy difficulty biology question is from the chapter structural organisation in animals and plants, covering the topic of plant tissue: meristems. It appeared in the 2025 exam.
