Yes, the cell membrane is primarily composed of lipids, specifically a type of lipid known as phospholipids. These phospholipids form a bilayer that serves as the fundamental structure of the cell membrane. This bilayer provides a flexible yet sturdy barrier that separates the cell's interior from its external environment. In addition to lipids, the cell membrane also contains proteins and carbohydrates, which are embedded within or attached to the lipid bilayer, playing various roles in cellular function, such as transport, communication, and structural support.
