  1. Archaea
    The domain of life containing anucleate cells that have unique lipids in their membranes, distinctive rRNA sequences, and cell walls that lack peptidoglycan
  2. Bacteria
    The domain of life that contains anucleate cells having distinctive rRNA sequences and cell walls that contain the structural molecule peptidoglycan
  3. Eukarya
    The domain of life that features organisms made of cells having a membrane-delimited nucleus and differing in many other ways from Archaea and Bacteria; includes protists, fungi, plants, and animals
  4. Fungi
    A diverse group of eukaryotic microorganisms that range from unicellular forms (yeasts) to multicellular molds and mushrooms
  5. Genome
    The entire genetic makeup of an organism
  6. Genomic Analysis
    An approach to studying organisms that involves sequencing the genome, identifying genes, and assigning functions to the genes
  7. Koch's Postulates
    A set of rules for proving that a specific microorganism causes a particular disease
  8. Microbiology
    The study of organisms that are usually too small to be seen with the naked eye; special techniques are required to isolate and grow them
  9. Microorganism
    An organism that is too small to be seen clearly with the naked eye and lacks highly differentiated cells and distinct tissues
  10. Prions
    Infectious agents, composed only of protein, that cause spongiform encephalopathies such as scrapie in sheep
  11. Prokaryotic Cells
    Cells having a type of structure characterized by the lack of a true, membrane-enclosed nucleus. All known members of Archaea and most members of Bacteria exhibit this type of cell structure
  12. Protists
    Mostly unicellular eukaryotic organisms that lack cellular differentiation into tissues. Cell differentiation is limited to cells involved in sexual reproduction, alternate vegetative morphology, or resting states such as cysts; includes organisms often referred to as algae and protozoa
  13. Spontaneous Generation
    An early belief, now discredited, that living organisms could develop from nonliving matter
  14. Viroids
    Infectious agents of plants composed only of single-stranded RNA
  15. Viruses
    Infectious agents having a simple acellular organization with a protein coat and a nucleic acid genome, lacking independent metabolism, and reproducing only within living host cells
  16. Virusoids
    Infectious agents composed only of single-stranded RNA. They are unable to replicate without the aid of specific viruses that coinfect the host cell
