In most of the plants, intercalary meristems are situated at the
Correct answer: C. Base of internodes
- A. Root apex
- B. Shoot apex
- C. Base of internodes
- D. Lateral sides of shoots
Explanation
Intercalary meristems are primarily found at the base of internodes in many plants and are responsible for the elongation of plant sections such as stems and leaves. This is especially common in grasses and monocots where growth needs to occur from the base upwards. The root apex and shoot apex are sites for apical meristems, which facilitate root and shoot elongation respectively. The lateral sides of shoots, however, are associated with lateral meristems, which are involved in the thickening of the plant stem or trunk (secondary growth).

About Plant Growth Regulators
Plant growth regulators are chemical messengers that control growth, development and responses to the environment. The topic covers auxins, gibberellins, cytokinins, abscisic acid and ethylene, including cell elongation, apical dominance, tropisms, seed germination, dormancy, fruit ripening and leaf fall, with growth promoters distinguished from inhibitors.
