Bacterial cells are smaller than eukaryotic cells, with some exception. Viruses are smaller than bacteria, with some exception. These are just two examples of why definitions in Biology, unlike in Physics and Chemistry, most often need to be qualified. What does this tell us about Biology?
Big fleas have little fleas,
Upon their backs to bite 'em,
And little fleas have lesser fleas,
and so, ad infinitum.
Anyone want to bet on when quarks will be smashed into smaller constituent particles?
