Which option gives the most accurate combined conclusion of both animal and plant parts of this chapter?
Answer and explanation
Correct answer: Animals coordinate through nerves and hormones while plants coordinate through chemicals and growth changes
The governing concept is coordination across different kinds of organisms. Animals use the nervous system for rapid electrical control and hormones for slower, sustained regulation. Plants lack a brain and nerves like animals, but chemical messengers and growth responses such as phototropism help them respond to stimuli. Thus option A correctly combines both parts. The other options wrongly give plants a brain, spinal cord, blood-based control, or an exclusive dependence on light.
