glycocalyx definition biology
The glycocalyx is a glycoprotein-polysaccharide covering that surrounds the cell membranes of some bacteria, epithelia and other cells.Most animal epithelial cells have a fuzz-like coat on the external surface of their plasma membranes.he glycocalyx exists in bacteria as either a capsule or a slime layer. 6 points at the glycocalyx. The difference between a capsule and a slime layer is that in a capsule polysaccharides are firmly attached to the cell wall, while in a slime layer the glycoproteins are loosely attached to the cell wall.
