Fluid mosaic model
The fluid mosaic model describes the structure of cell membranes. It depicts the membrane as a flexible layer made of various molecules, primarily lipids and proteins, which float and move within it. The "fluid" aspect indicates that these components are not fixed in place, allowing for movement and flexibility. The "mosaic" part refers to the diverse array of proteins that are scattered throughout the lipid layers, resembling a mosaic artwork. This model helps explain how substances enter and exit cells, how cells communicate, and how they maintain their shape while adapting to different conditions.

The Fluid Mosaic Model describes the structure of cell membranes. Imagine a flexible and dynamic sea where various proteins float among a double layer of lipids (fats). This “mosaic” of proteins helps the cell interact with its environment, facilitating communication and transport. The “fluid” aspect indicates that these components can move around, allowing the membrane to change shape and adapt to different functions. Overall, this model illustrates how the membrane is both structured and adaptable, crucial for maintaining the cell's integrity and function.
