What is the function of the plasma membrane?
1 answer
The plasma membrane, also known as cell membrane, serves as a barrier to separate the internal environment of the cell from the external environment. It is selectively permeable, which means it regulates the passage of molecules and ions in and out of the cell. The plasma membrane is also involved in cellular communication and recognition, as it contains various proteins and receptors that interact with other cells and signaling molecules. Additionally, the plasma membrane provides structural support and shape to the cell.
