Biology AS - Plasma membrane

The Plasma Membrane is the outer body of the Protoplast.

Many of the proteins in the outer part of the membrane are carrier proteins, which transport substances across the membrane.

The membrane is viewed as a fluid mosaic model.

This suggests that the protein component of the membrane is patchy, like a mosaic!

The exterior of the cell membrane of animal cells is called the cell coat.

it is made of mucopolysaccharides, glycolipids, glycoproteins and aluronic acid.

The cell coat is sticky, allowing it to adhere to other animal cells
