Frequently Asked Questions

Are viruses considered to be living organisms essay?

Viruses can be regarded non living as they are acellular and require a host to perform its metabolic and reproductive activities. Viruses are convoluted assemblage of molecules, including nucleic acids, proteins, carbohydrates and lipids, but unable to do anything on their own until they penetrate the host cell.

Which argument supports the idea that viruses are alive?

The argument that supports the idea that viruses are alive is that B. viruses contain unique genetic information, just like humans do. Having a cell membrane doesn't necessarily make the organism alive. Not producing proteins also doesn't mean that an organism is alive, because living things do produce protein.

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.

Is a virus a living thing why or why not?

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.
