Microbiology Intro

  1. List some applications of Microbiology
    • Food Production
    • Bioremediation
    • Useful products from bacteria
  2. What is biodiversity?
    The variety of species inhabiting a particular environment.
  3. What is a domain?
    The highest level in classification above the level of kingdom.
  4. What are the 3 domains all organsism can be assigned to?
    • Bacteria
    • Archaea
    • Eucarya
  5. What is a Eukaryote?
    • Organism composed of one or more eukaryotic cells
    • members of the domain "Eukarya" are eukaryotes.
  6. What is a eukaryotic cell?
    Cell characterized by a membrane bound nucleus.
  7. What is a Prokaryote?
    Single celled organism composed of prokaryotic cells.
  8. What is a Prokaryotic Cell?
    Cell type characterized by lack of a membrane bound nucleus or any other intracellular organelles.
  9. What is the nucleoid?
    The region of a prokaryote that contains DNA.
  10. Which 2 domains belong to the prokaryote group?
    • Bacteria
    • Archaea
  11. Give an example of eukaryotes:
    • Algae
    • Fungi
    • Protozoa
    • Multi-cellular parasites
  12. Compare the cell walls of Bacteria, Archaea, and Eucarya:
    • Bacteria - has Peptidoglycan present, which causes the wall to be rigid.
    • Archaea - No Peptidoglycan
    • Eucarya - No Peptidoglycan
  13. Compare nuclear membranes of Bacteria, Archaea, and Eucarya:
    • Bacteria: No membane
    • Archaea: No membane
    • Eucarya: Has membrane
  14. Discuss the organelles of Bacteria, Archaea, and Eucarya:
    • Bacteria: No organelles
    • Archaea: No organelles
    • Eucarya: Organelles
  15. How do Bacteria and Archaea multiply?
    Binary Fission
  16. What is a virus?
    A piece of nucleic acid surrounded by a protien coat that can only reproduce inside living cells.
  17. What is a viroid?
    A simple, short piece of ribonucleic acid without a protective coating, that can only reproduce within a living cell.
  18. What are prions?
    Structure that consists only of abnormal protiens, with no nucleic acid, responsible for at least 7 neurodegenerative diseases in humans and animals.
