Although cells are an important component of all living organisms, a virus is typically a parasite. They therefore lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane. It has since evolved into the current parasitic form of viruses that we see today. In addition to viruses, virions are also forms of non-cellular life. The virus resides inside a host cells cytoplasm while the cell lives outside of it.
