The cell membrane, also known as the plasma membrane, is a thin layer of lipid and protein molecules that surrounds the cell. It acts as a gatekeeper, controlling the movement of materials in and out of the cell. This selective permeability allows the cell to maintain a stable internal environment, known as homeostasis, which is crucial for proper cellular function. The cell membrane's structure, composed of a phospholipid bilayer with embedded proteins, enables it to regulate what enters and leaves the cell, making it a critical component of cellular function.
