Note that cellular organisms exclude viruses. 2019-08-12T18:01:37Z A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex but below that of an anatomical system. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. Components are larger than individual macromolecular entities. It is tricky to define distinction between 'cell component' and 'macromolecular entity', e.g. ribosome. We would like to exclude most protein complexes.
