Florigen is produced by:
Correct answer: C. Leaves (CORRECT)
- A. Flowers
- B. Flower-buds
- C. Leaves (CORRECT)
- D. Fruits
Explanation
Florigen is a plant hormone produced in the leaves. It acts as a long-distance signaling molecule that travels to the shoot apical meristem, promoting the transition from vegetative growth to flowering. This process is crucial for the plant's reproductive success. Option C is correct because leaves are where this hormone is synthesized. Options A, B, and D are incorrect as flowers, flower-buds, and fruits do not produce florigen. They play roles in the reproductive cycle of plants but are not the source of this specific hormone.

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.
