How is chemical coordination in plants different from nervous coordination in animals?
Answer and explanation
Correct answer: In plants, responses usually occur through chemicals and growth changes, whereas animals use rapid nerve signals
Plants do not possess a nervous system with a brain, spinal cord, and specialised nerves. Their coordination commonly depends on chemical messengers such as plant hormones, which alter growth or other physiological activities and may act relatively slowly. Animals use electrical impulses in neurons, often producing rapid responses, with hormones also supporting longer-term control. Thus option A gives the valid comparison.
