Glycocalyx - an outer layer that provides protection. It is an important virulence factor since it protects disease-causing bacteria. It helps bacteria hold on to surfaces and protects disease-causing bacteria. It helps bacteria hold on to surfaces and protects them from being engulfed by macrophages. It may exist as a rigid capsule or a more unstructured slime layer.
Two. Cell wall - a structure that confers rigidity and shape to the cell. It is found outside of the plasma membrane and is composed of peptidoglycan. Three. Plasma membrane - a structure that prevents the loss of water and electrolytes inside the cell. It also prevents the entry of unwanted substances into the cell. It is composed of phospholipid bilayer.
Four. Plasmid - a small, circular, extrachromosomal DNA molecule found in the cytoplasm. It is separate from chromosomal DNA. Five. Nucleoid - the region where DNA is concentrated. Six. Cytoplasm - the whole inside region of the cell where chromosomes, ribosomes, and other cellular inclusions are suspended. Seven. Ribosome - the site where proteins are synthesized or created. Eight. Pilus (plural, pili) - a short, hairlike appendage on the surface of some bacteria. It helps bacteria adhere to the surfaces of host cells. It can also be used to transfer genetic material from one bacterium to another; in which case it is called sex pilus.
Nine. Flagellum (plural, flagella) - a long, structure that facilitates movement in bacteria. Ten. Fimbriae - bristle-like fibers that are shorter than pili. It is primarily used for bacterial attachment to tissue surfaces.
