Answer 3: Viruses are not considered alive because they lack many of the properties that scientists associate with living organisms. Primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell-division approach to replication.nswer 3: Viruses are not considered alive because they lack many of the properties that scientists associate with living organisms.

Viruses are similar to, but not considered, living organisms. To be considered living, an organism must be able to reproduce, either asexually or sexually.Viruses, however, are only able to replicate themselves by commandeering the reproductive apparatus of the cells of living beings and making them reproduce the virus's genetic structure instead.hus, a virus cannot function or reproduce outside of another being's cell, thereby being totally dependent on a host cell in order to survive. Most viruses are species specific, and related viruses typically only infect a narrow range of plants, animals, bacteria, or fungi.
