Can you provide a comprehensive cell membrane review in the context of cellular biology?

The cell membrane is a vital structure in cellular Biology, serving as a protective barrier that controls the movement of substances in and out of the cell. It is composed of a phospholipid bilayer with embedded proteins that help regulate the transport of molecules. The membrane also plays a role in cell signaling and communication with other cells. Overall, the cell membrane is essential for maintaining the integrity and function of the cell.
