Which of the following is NOT a function of the cell membrane?

• A. Regulate what enters and exits the cell
• B. Provide structural support to the cell
• C. Facilitate communication between cells
• D. Store genetic information

Answer: (D)

The cell membrane plays several essential roles in the life of a cell. It is primarily responsible for regulating the passage of substances into and out of the cell, thus maintaining the internal environment. The membrane also facilitates communication between cells through receptors that can send signals in response to external stimuli, contributing to the coordination of cellular activities. Structural support is also a function of the cell membrane, as it provides a boundary that helps maintain the shape of the cell. It acts as a protective barrier, helping to keep the internal contents intact while also being flexible enough to allow for movement. Storing genetic information is not a function of the cell membrane. Instead, genetic information is found within the nucleus of eukaryotic cells or in the nucleoid region of prokaryotic cells. The nucleus contains DNA, which carries the instructions for the cell's functions and is essential for reproduction and cellular processes. Thus, storing genetic information is unrelated to the primary functions of the cell membrane.
