Frequently Asked Questions

Why do scientists not consider viruses alive?

The major reason that many biologists do not consider viruses to be alive is the fact that they can not reproduce on their own. Instead of reproducing on their own (either sexually or asexually), viruses have to use their hosts' cellular mechanisms to reproduce themselves.

Are viruses considered living or nonliving?

Viruses are considered to NOT be a nonliving because they lack many properties of living organisms. Viruses don't have the ability to make their own chemical products and need a host cell to do that for them. That is why they can't reproduce without a host cell.

Should a virus be considered a living organism?

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.
