WebS layers help maintain overall rigidity of the cell wall and surface layers, as well as cell shape, which are important for reproduction. S layers protect the cell from ion/pH changes, osmotic stress, detrimental enzymes, bacterial viruses, and predator bacteria. They can provide cell adhesion to other cells or surfaces. For pathogenic bacteria ... WebThe bilayer cell membrane is also termed as “ Plasma membrane ”. The cell membrane allows the exchange of only specific or selective molecules between the cell and surrounding, i.e. it serves as a selectively permeable membrane. A cell membrane primarily composed of 40% lipid, 60% protein and 1-10% of carbohydrate of dry cell weight.
