The plasma membrane, also known as the cell membrane, serves as a protective barrier that regulates the movement of substances into and out of the cell. It is found in all types of cells, including animal cells, plant cells, and bacterial cells. The plasma membrane is crucial for maintaining cellular homeostasis and participating in various cellular processes like cell signaling and transport.
The function of the plasma membrane is to regulate the movement of substances in and out of the cell. It serves as a protective barrier and allows the cell to maintain its internal environment. The plasma membrane is found in all types of cells, including both prokaryotic and eukaryotic cells.
