<Could anyone tell me the differences between prokaryotic cells,
cells and viruses?>
Very basically (I'm not sure if you're just curious, or if I'm doing your
homework, which I don't want to do really):
1. Prokaryotes: Cells which do not contain a nucleus or organelles (other
than ribosomes). Bacteria (unicellular life forms) constitute prokaryotes.
2. Eukaryotes: Cells which do contain a nucleus and organelles. They may
be unicellular life forms (such as protozoa or plankton) or individual
cells of multicellular organisms such as plants, animals or human beings.
3. Viruses: Submicroscopic, noncellular entities which consist only of
genetic material (can be DNA or RNA) and a protein coat (capsid), with or
without a lipoprotein envelope around the capsid.
