Fluid-mosaic model
The Fluid Mosaic Model is used to explain the components and properties of the plasma membrane. This model describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move and interact within the membrane.

The fluid mosaic model is commonly used to explain the structure and function of the plasma membrane. It describes the membrane as a fluid lipid bilayer with embedded proteins that can move laterally, giving the membrane its dynamic nature. The model helps illustrate how the plasma membrane controls the passage of substances into and out of the cell.
The three main components of a eukaryotic cell is the plasma membrane, cytoplasm, and nucleus. The plasma membrane consists of proteins, phospholipids, and cholesterol.

Ribosomes are not major components of the cell plasma membrane. However, the Golgi Apparatus and Endoplasmic Reticulum (ER) are major components of the cell plasma membrane. The Golgi Apparatus is involved in modifying, sorting, and packaging proteins for secretion, while the ER is responsible for protein synthesis and lipid metabolism.
Proteins are dispersed throughout the plasma membrane along with cholesterol molecules. These components help maintain the structure and functions of the membrane.
A plasma membrane is described as mosaic because all the different components such as proteins and phospholipids, of varying shape and size, give the effect of the stones of a mosaic. It is described as fluid because these components can move freely within the membrane.
Approximately 50% of the plasma membrane is made up of fatty acids, which are essential components of phospholipids forming the lipid bilayer of the membrane. These fatty acids provide the plasma membrane with flexibility and help regulate its fluidity.
