What is the main message of the chapter Control and Coordination?

Answer and explanation

Correct answer: Organisms detect external changes and give suitable responses

The governing idea of control and coordination is that organisms detect stimuli or changes in their surroundings and then produce suitable responses. Animals may use receptors, nerves, the brain, and hormones, while plants mainly use chemical signals and growth responses. Thus option A gives the complete chapter message. Options B, C, and D are false because organisms do respond and both plants and animals show coordination.
