The cell membrane, also known as the plasma membrane, is primarily composed of a phospholipid bilayer, which provides a barrier and supports the structure of the cell. It contains various proteins, carbohydrates, and cholesterol that assist in cell signaling, transport, and communication. The membrane's fluid nature allows for the movement of these components, facilitating various cellular functions. Overall, the quantity and arrangement of these molecules are crucial for maintaining homeostasis and regulating interactions with the environment.
