Which statement best describes cellular communication?

The statement that healthy cells communicate to function for the whole organism accurately reflects the essential nature of cellular communication. In multicellular organisms, cells are not isolated entities; they rely on communication for coordination and cooperation. This communication occurs through signaling molecules, which can include hormones and neurotransmitters, allowing cells to share information about their status and adjust their functions accordingly.

Healthy cells engage in communication to maintain homeostasis, respond to environmental changes, and ensure that all cells work synergistically towards the overall functioning and health of the organism. This cooperative behavior is crucial for processes like growth, immune responses, and tissue repair.

In contrast, the other options suggest a disconnection between cells or imply communication is only relevant in unhealthy contexts, which does not accurately represent the dynamic interactions that are vital for the well-being of an organism.
