What is another term used to refer to the cell membrane?

The cell membrane is also known as the plasma membrane. This term emphasizes its role in maintaining the integrity of the cell by enclosing its contents and regulating the movement of substances in and out of the cell. The plasma membrane is composed of a phospholipid bilayer with embedded proteins, which play crucial roles in signaling, transportation, and maintaining the structure of the cell.

Understanding the distinction between the plasma membrane and other cellular components is essential. For instance, the cell wall is a rigid structure found in plant cells and some prokaryotes that provides additional protection and support, while the cytoplasm refers to the jelly-like substance within the cell that houses organelles. The endoplasmic reticulum is an organelle involved in protein and lipid synthesis. Therefore, plasma membrane is the accurate term that aligns with the function and structure of the cell membrane.
