Which of the following best describes the communication process in cells?

• A. Cells communicate by sending and receiving chemical signals.
• B. Cells communicate through direct physical contact only.
• C. Cells communicate by exchanging genetic material.
• D. Cells communicate exclusively through electrical impulses.

Answer: (A)

Verified step by step guidance

1. Understand that cell communication is a fundamental process in physiology, allowing cells to coordinate and respond to their environment.
2. Recognize that cells communicate through various mechanisms, including chemical signals, which are crucial for processes like hormone signaling and neurotransmission.
3. Consider the role of direct physical contact, such as gap junctions, which allow ions and small molecules to pass directly between adjacent cells.
4. Evaluate the exchange of genetic material, which is not a typical form of communication but occurs during processes like conjugation in bacteria.
5. Acknowledge that electrical impulses are primarily used in nerve cells for rapid communication, but are not the exclusive method of communication in all cells.
