Solution

The plasma membrane is considered a fluid mosaic model due to its dynamic nature where lipids and proteins move laterally within the layer. The stability of this model is provided by cholesterol. Cholesterol is a type of lipid that is wedged between the fatty acid chains of the phospholipids that make up the bulk of the membrane. This helps to prevent fatty acid chains from coming together and crystalizing, thus maintaining the fluidity of the membrane. Additionally, cholesterol also helps to prevent the membrane from becoming too fluid at higher temperatures. Therefore, cholesterol plays a crucial role in maintaining the stability of the fluid mosaic model of the plasma membrane.
