A bacterium is a single-celled, often parasitic microorganism without a distinct nucleus or an organized cell structure. It has cytoplasm and a cell wall, but no true nucleus. Various species are responsible for decay, fermentation, nitrogen fixation, and many plant and animal diseases.

Bacteria are classed in a kingdom of their own, prokaryota (although, this kingdom may now be regarded as two separate kingdoms, archaea and bacteria).

A virus is a submicroscopic parasitic particle consisting of a strand of nucleic acid surrounded by a protein coat (capsid). It does not have cytoplasm or a nucleus and can only replicate within a host cell (has parasitic nature).

Viruses are not considered to be independent living organisms as the only characteristic of life they show is reproduction.
