living structure, such as a plant, animal,
fungus or bacterium, capable of growth and reproduction. The definition "any life form capable of independent reproduction, organic or otherwise" would
encompass all cellular life, as well as the possibility of synthetic life capable of independent reproduction,
but would exclude viruses, which are dependent on the biochemical machinery of a host cell for reproduction. Some may use a definition that would also include viruses" -- Source Reference Wikipedia.org back to 26)
