Everything about Cellular Life totally explained
Cellular life is
life with
cells. The usual meaning of
life as we know it expects that an organism have either
unicellular or
multicellular structure.
But implied by the modifier "cellular" is the existence of earth-based life that's
non-cellular. This point of view usually includes the
classification of
viruses as lifeforms.
In discussing the
domains of life, the term
Cytota is occasionally used as a
kingdom, domain, or
empire name to distinguish
cell-based life from the
non-cellular life (labelled
Acytota). Both would be the only two subdivisions of earthly life -- also known as terrestrial organisms,
Biota,
Naturae, or Vitae.
The issue of life being both cellular
and non-cellular has recently come to the fore due to the 2003 discovery that the
Mimivirus is very large, had genes for hundreds of proteins and can make some
proteins that are involved in the synthesis of other proteins. This finding has suggested to some
virologists and
bacteriologists that there should be a fourth -- that is,
viral -- domain of life, in addition to the cellular
domains of
Archaea,
Bacteria, and
Eukaryota.
