The cell capsule is a very large structure of some prokaryotic cells, such as bacterial cells. A true capsule is a discrete detectable layer of polysaccharides deposited outside the cell wall. A less discrete structure or matrix which embeds the cells is a called a slime layer or a biofilm. The capsule found in bacteria called a glycocalyx.
