How is bacteria and virus dfferent?

Answer 1

Bacteria diseases are treatable; while virus diseases have never been treated, but we can make vaccines for them.

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.
A bacteria is a living organism - same as you but smaller (and much simpler),

whereas a virus is only genetic code (plus a protein coat for survival [and attack].

A virus in not alive, and can even be crystallized.

Answer 2

Viruses cannot divide or grow on their own; they can only divide and multiply when they infect a host organism. Viruses that infect bacteria are known as bacteriophages.

Bacteria can divide on their own and multiply; they have their own intracellular mechanisms for generating energy from substrates such as sugar (or other).

In essence bacteria are independent living organisms where as viruses are not.

Answer 3

Bacteria, like archea, are prokaryotic cells. They lack a nucleus and membrane bound organelles. However, some species of bacteria have a flagellum and a cell wall.

Viruses, in a sense, are not cells, and are not considered living organisms. Although they do have DNA, they require a living organism (a "host", you could say) in order to reproduce.

Answer 4

The difference between the two is considerable. The bacterial cell is much larger and most of all it is alive. The virus is very small and not alive.
