Question

Are viruses Alive? :-)

Answer 1

Viruses are category as acellular.

Viruses are dead when present in environment but they become alive when they are present in a living body and uses that as a host.

Thus they do not follow the cell theorey.
We can't say viruses are alive or dead.

Answer 2

First seen as poisons, then as life-forms, then biological chemicals, viruses today are thought of as being in a gray area between living and nonliving: they cannot replicate on their own but can do so in truly living cells and can also affect the behavior of their hosts profoundly.
