Answer:
Viruses replicate only inside host cells.
Explanation:
<u>Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells. </u>
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
<em>Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory. </em>
