Chemical coordination in plants occurs through what?
Answer and explanation
Correct answer: Plant hormones
Plants lack the nervous system and specialised neurons found in animals, but they still coordinate growth and responses. They do this through chemical messengers called plant hormones or phytohormones, including auxin, gibberellin, cytokinin, ethylene, and abscisic acid. Neurons, bones, and blood cells are animal structures, not the plant mechanism. Thus, option A is correct.
