Why is it called the fluid mosaic model?
Understand the Problem
The question is asking for an explanation of the term 'fluid mosaic model,' which refers to a specific model describing the structure of cell membranes. The question seeks to understand the reasoning behind this naming and the key components of the model.
Answer
The cell membrane is composed of various molecules that float and move fluidly, resembling a mosaic made of different tiles.
The final answer is that the cell membrane is described as the fluid mosaic model because it is composed of various molecules, such as phospholipids and proteins, that float and move fluidly, resembling a mosaic made of many different tiles.

More Information
The fluid mosaic model was first proposed by S.J. Singer and Garth L. Nicolson in 1972. The 'fluid' aspect refers to the lateral movement of lipids and proteins within the layer, while 'mosaic' highlights the diverse components within the membrane.
Tips
A common mistake is thinking of the cell membrane as a static structure. It is actually dynamic with components that frequently move within the layer.
