Verified step by step guidance

Understand the context of signaling in both plants and animals. Signaling refers to the process by which cells communicate with each other to coordinate their functions.

Recognize that both plants and animals have developed unique signaling mechanisms due to their different evolutionary paths and environmental challenges.

Consider the differences in mobility: Animals can move to respond to stimuli, while plants are stationary and must adapt their signaling to environmental changes.

Examine specific signaling pathways: For example, animals often use hormones like adrenaline for rapid response, while plants use hormones like auxins to regulate growth and response to light.

Conclude that due to these differences in lifestyle and environmental interactions, plant and animal signaling systems have indeed evolved differently, supporting the statement as true.
