Structural components of bacteria

BACTERIAL STRUCTURE Cell Envelope: Four(4) layers are Capsule/ Slime layer Outer membrane Cell wall Inner membrane When the layer consists of a network of polysaccharides extending from the surface of the cell, it is referred to as the glycocalyx, a term that can...

Bacterial Staining

All the bacterias are colorless and have some refractive index to the aqueous salt present in the surrounding.So it is difficult to observe structural details until the microscope is optimally adjusted.To overcome this problem the bacterias are colored with stains....
