What does the “fluid mosaic model” mean about the cell membrane?
A
It can dissolve into fluid.
B
The cell is mostly made of mosaic molecules.
C
It looks like a flexible pattern made up of different parts.
D
Somebody else should name these things.
Explanation: 

Detailed explanation-1: -The fluid mosaic model was proposed by S.J. Singer and Garth L. 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. These components give a fluid character to the membranes.

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: -The fatty acids of most natural phospholipids have one or more double bonds, which introduce kinks into the hydrocarbon chains and make them difficult to pack together. The long hydrocarbon chains of the fatty acids therefore move freely in the interior of the membrane, so the membrane itself is soft and flexible.

Detailed explanation-4: -The fluid mosaic model of the cell membrane describes how the membrane is fluid, flexible and made of many different components or macromolecules.
