Final answer:
The fluid mosaic model describes the plasma membrane as a mosaic of components, including phospholipids, cholesterol, proteins, and carbohydrates, resulting in a fluid character. Integral membrane proteins are embedded in the phospholipid bilayer and play roles in transport and reception.
Step-by-step explanation:
The fluid mosaic model is a model that describes the structure of the plasma membrane as a mosaic of components, including phospholipids, cholesterol, proteins, and carbohydrates. These components give the membrane a fluid character, meaning they can move laterally within the membrane. The model proposes that integral membrane proteins are embedded in the phospholipid bilayer, with some extending through the bilayer and others partially across it. These proteins play important roles in transport and reception.
