Viruses are LIKE living things because: –they contain a nucleic acid, either DNA or RNA –they have a coat made of protein Viruses are NOT LIKE living things because: –viruses are not made of cells (no cytoplasm, plasma membrane, etc.) –viruses do not use energy –viruses do not exchange gases with the environment –viruses do not reproduce themselves When we list the kingdoms of living things, viruses are not in any of the kingdoms.

Because when viruses are outside the body of a living organism they show symptoms of non-living things. And as they enter the body of living organism they show symptoms of living things ie:- they replicate. They also contain DNA or RNA which signifies that they are living.

In order to be regarded as a living thing you must be able to copy/reproduce yourself. Viruses must invade the cell and then trick it into thinking its part of its DNA make up. When the cell divides and reproduces then the virus. That is not the complete answer but I hope it helps.
