It is composed of a phospholipid bilayer with embedded proteins, and it serves as a barrier between the cell and its environment, regulating the passage of molecules and ions in and out of the cell. The cell membrane also plays a crucial role in cell signaling and communication, as it contains receptors for various molecules and can transmit signals from the outside to the inside of the cell. Additionally, it provides structure and support to the cell, allowing it to maintain its shape. The cell membrane is a dynamic and constantly changing structure that can rearrange itself and alter its permeability based on the needs of the cell.
