Why Is the Cell Membrane Called a Fluid Mosaic?

💡 The Answer

• The fluid mosaic model describes the membrane as a dynamic lipid bilayer with embedded proteins.
• Proteins and lipids can move laterally within the membrane, giving it fluid-like properties.
• The term mosaic refers to the diverse array of proteins that float in the phospholipid sea.
• This model was proposed by Singer and Nicolson in 1972, revolutionizing cell biology.
