Q. Coordination in plants is by
✅ Correct Answer: (C)
hormones
Explanation:
Plants do not have a nervous system like animals. Instead, they coordinate their functions through plant hormones (also called phytohormones). These hormones regulate growth, development, and responses to environmental stimuli.
Some key plant hormones include:
- Auxins – Control cell elongation and phototropism.
- Gibberellins – Promote stem elongation and seed germination.
- Cytokinins – Promote cell division.
- Abscisic Acid (ABA) – Helps in stress responses and stomatal closure.
- Ethylene – Involved in fruit ripening.
Thus, hormones are responsible for coordination in plants.
