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.
D
Somebody else should name these things.
Explanation: 

Detailed explanation-1: -The fluid mosaic model is a way of describing the structure of cell membranes. The model likens the membrane to a “mosaic” of different components, consisting of a fluid or elastic double layer made up of lipid molecules and large protein molecules.

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 cell membrane is flexible enough to form invagination around a particle and to take it inside the cell. This process is termed as endocytosis or sometimes phagocytosis. Cell membrane can also fuse to the vesicular membrane and can release vesicular contents to the external medium.

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.
