Cell membrane
Scientist for an extended period has tried to explain how the cell membrane functions, by looking at how the membrane seems alike. The cell membrane is sometimes referred to as fluid model because mainly it is made up of a bunch of varying molecules that are distributed all over the membrane. Looking closely to the cell membrane, you are likely to see that there is a varying pattern of types of molecules that are grouped together, this grouping is sometimes referred to mosaic.
The molecules in the cell membrane move in two dimensions continuously; this movement can be compared to the movement of icebergs that is floating in the ocean. This mosaic movement makes it hard for the membrane to be impenetrable ultimately. The mosaic movement makes the membrane to be penetrable.
Some factors lead to membrane fluidity. The mosaic nature of the cell membrane, helps the plasma membrane to remain fluid—the presence of integral lipids and proteins in the layer as separate and attached loosely. If the membrane takes too much water, it can burst since it is not rigid due to mosaic nature a very fine needle can find its way into the membrane, without bursting it. It will seal the membrane.
Mosaic model
The structure of the cell membrane is described as mosaic because it includes phospholipids, cholesterol carbohydrates and proteins, that makes membrane to be in a fluid state. Mosaic nature of the cell plasma describes plasma cell membrane as a fluid combination. Components of cell membrane such as phospholipids, cholesterol, and proteins, together with carbohydrates that are attached to lipids(glycolipids) and also attached to proteins protrude surface of the plasma cell membrane outwards.
