Control and coordination in plants mainly occur through what?
Answer and explanation
Correct answer: Through chemical substances
Plants do not possess a brain, spinal cord, or a nervous system like animals. Their control and coordination mainly depend on chemical messengers called plant hormones, together with local growth responses and changes in cells. Therefore option A is correct. Nerves, the brain, and the spinal cord are parts of animal nervous coordination, so options B, C, and D are unsuitable for plants.
