    1. Viruses are considered as an intermediate between living and non-living cells because they cannot metabolite and reproduce on their own. They can reproduce only when enters in a host's body. They are an exception to cell theory. A virus crystal is a collection of thousands of viruses. A viral crystal is a pore collection used for chemical studies.
