The cell membrane is primarily composed of a lipid bilayer with embedded proteins (fluid mosaic model). This structure is flexible and allows the cell to change shape and engulf substances from the external environment through processes like endocytosis (e.g., phagocytosis and pinocytosis), which is essential for functions like nutrition or defence.
