Viruses are non-living organisms because they are acellular, that is, they contain no cytoplasm or cellular organelles but are merely parasitic chemicals. However, they do reproduce at an accelerated rate, but only in living host cells.

The six kingdoms of life consist of all living things that have basic common characteristics. The common characteristics are as follow; cellular organization, metabolism, homeostasis, growth and reproduction, and heredity. From their common characteristics, they are next categorized into six groups called Kingdoms; Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia.
