How is control and coordination possible in plants even without a nervous system?
Answer and explanation
Correct answer: Through plant hormones and growth responses
The governing concept is chemical and growth-based coordination in plants. Plants lack a nervous system, bones and muscles, but they produce hormones that move through tissues and influence cell division, elongation and responses to light, gravity or water. These slow chemical signals and directional growth responses coordinate plant activities. A spinal cord, brain, heart and animal-style blood circulation are therefore not the explanation.
