Answer 1

The viruses are non-cellular obligate parasites that are characterized by having an inert crystalline structure outside the living cell. Once the viruses infect a cell, they kill the host cell and take over the machinery of the host cell to replicate themselves.

Viruses (Virus particles or virions) are usually units consisting of nucleic acids and coat proteins called capsids. Viroids consist only of RNA, i.e. they contain no protein at all. Except for a few cases, viruses are not surrounded by a membrane.
