Detailed explanation-1: -Phospholipid bilayer with embedded proteins describes the fluid-mosaic model of the plasma membrane structure.

Detailed explanation-2: -The fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.

Detailed explanation-3: -Which of the following statements best describes the fluid mosaic model of the plasma membrane? right answer feedback: The fluid mosaic model of the plasma membrane is composed of two layers of lipid molecules with protein molecules dispersed within.

Detailed explanation-4: -Cell membranes are represented according to a fluid-mosaic model, due to the fact that they are: Fluid – the phospholipid bilayer is viscous and individual phospholipids can move position. Mosaic – the phospholipid bilayer is embedded with proteins, resulting in a mosaic of components.

Detailed explanation-5: -The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components-including phospholipids, cholesterol, proteins, and carbohydrates-that gives the membrane a fluid character.
