What name is used to identify the cell membrane?
A
fluid-mosaic model
B
The solid/liquid model
C
Fatty acid model
D
The Cytoplasmic model
E
The Epidermal layer
Explanation: 

Detailed explanation-1: -Nicolson. This model explains the structure of the plasma membrane of animal cells as a mosaic of components such as phospholipids, proteins, cholesterol, and carbohydrates.

Detailed explanation-2: -The cell membrane, whose structure is described in the fluid mosaic model, is also called the plasma membrane or the plasmalemma.

Detailed explanation-3: -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-4: -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.

Detailed explanation-5: -The fluid mosaic model of the cell membrane is called such because the cell membrane is made of different parts working together, like a mosaic is made of many tiles. The different parts of the cell membrane include: Phospholipids. Cholesterol.
