Which of the following is an accurate statement about cell communication?

• A. Cell communication is primarily a function of the cell membrane's structural proteins.
• B. Cell communication only occurs in multicellular organisms.
• C. Cell communication involves the transmission of signals through direct contact or chemical messengers.
• D. Cell communication is independent of receptor proteins on the cell surface.

Answer: (C)

Verified step by step guidance

1. Understand that cell communication is a fundamental process that allows cells to interact with each other and their environment. It is crucial for maintaining homeostasis and coordinating functions within an organism.
2. Recognize that cell communication can occur through various mechanisms, including direct contact between cells and the use of chemical messengers such as hormones and neurotransmitters.
3. Identify the role of receptor proteins on the cell surface, which are essential for receiving and processing signals. These proteins bind to specific molecules, triggering a response within the cell.
4. Acknowledge that cell communication is not limited to multicellular organisms. Even unicellular organisms, like bacteria, communicate with each other to coordinate activities such as quorum sensing.
5. Clarify that structural proteins in the cell membrane are not primarily responsible for cell communication. Instead, receptor proteins and signaling molecules play a central role in transmitting and receiving signals.
