Virusy nie su vseobecne povazovane za zive organizmy, lebo jednak im chyba bunkova struktura, a tiez nie su schopne sa samostatne reprodukovat, ale potrebuju na to replikacny aparat hostitelskej bunky. Takze kedze virus nie je nikdy zivy, nemoze byt ani mrtvy :)

Viruses are considered by some biologists to be a life form, because they carry genetic material, reproduce, and evolve through natural selection, although they lack the key characteristics, such as cell structure, that are generally considered necessary criteria for defining life. Because they possess some but not all such qualities, viruses have been described as "organisms at the edge of life",[10] and as replicators.
