Viruses do not have cells (we agreed that living things have cells in our class consensus). Viruses do have a protein coat covering their genetic material, but they do not have a cell membrane or other organelles. All other living things are made up of one or more cells, which is a reason why viruses are not alive.
Viruses don’t feed or grow. They don't take in nutrients and they do not grow and increase in biomass when attacking a host cell. They only hijack the cell to make the virus replicate, losing a very small amount
