  1. What is microbiology?
    Study of small things that cannot be seen with the naked eye
  2. _?_, the study of bacteria, began with van Leewenhoek's first examination of tooth scrapings.
  3. _?_, the study of fungi, includes medical, agricultural, and ecological branches.
  4. _?_, the study of protozoa and parasitic worms.
  5. _?_, the study of all of an organisms genes, have allowed scientists to clarify bacteria and fungi according to their genetic relationships with other bacteria, fungi, and protozoa.
  6. _?_, the study of immunity, dates back in Western culture to Edward Jenner's first vaccine in 1796.
  7. _?_, the study of viruses, originated during the Golden Age of Microbiology (period from 1857-1914).
  8. Anyway of organizing or classifying things is _?_.
  9. The old view of taxonomy involved _?_.
    • 5 kingdoms:
    • Bacteria
    • Protists
    • Fungi
    • Plants
    • Animals
  10. The classification scheme based on evolutionary relationships using DNA is called _?_.
  11. The genus name is the _?_ and is _?_, while the specific epithet is not _?_ but is_?_ and refers to the _?_.
    first name; capitalized/italicized; capitalized; italicized; species
  12. The most specific level in the taxonomy hierarchy is known as _?_.
  13. _?_ defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance.
    Species Concept
  14. What is a domain?
    Taxonomic classification based on rRNA sequences.
  15. What is a kingdom?
    Taxonomic classification between domain and phylum.
  16. What is a phylum?
    Taxonomic classification between kingdom and class.
  17. Who was the first to suggest and publish his studies on DNA sequence of a wide variety of cells, suggesting the existence of a completely new major phylogenectic group called Archaea and proposed the 3 domain system?
    Carl Woese
  18. What is the three domain system?
    • Bacteria
    • Archaea
    • Eukarya
  19. Relatively simple, single-celled (unicellular) organisms are called _?_.
  20. Bacterial cells are called _?_ because their genectic material is not enclosed in a special nuclear membrane.
  21. This domain consist of prokaryotic cells, but if they have cell walls, the walls lack peptidoglyn.
  22. An organism whose cells have a distinct nucleus containing the cells's genetic material (DNA), surrounded by a special envelope called the nuclear membrane are known as _?_.
  23. _?_ are chemoheterotrophs and aqcuire food for absorbtion.
  24. Term used for unicellular and simple multicellular eukaryotes; usually protozoa and algae.
  25. _?_ are unicellular eukaryotic microbes that move by pseudopods, flagella, or cilia.
  26. Organisms that derive nutrients from living hosts are known as _?_.
  27. _?_ are photosynthetic eukaryotes with a wide variety of shapes and both sexual and asexual reproductive forms.
  28. _?_ are so small that most can be seen only with an electron microscope and are acellular (not cellular).
  29. The two major groups of parasitic worms are the flatworms and the roundworms, collectively called _?_.
  30. The theory that believed first Eukaryota came from prokaryotic cells is called _?_.
    Endosymbiotic theory
  31. The endosymbiotic theory was first proposed by _?_ in 1966.
    Lynn Margulis
  32. Which scientist created the first microscope?
    Anton van Leewenhoek
  33. _?_ was the first to actually observe live microorganisms through the magnifying lenses of more than 400 microscopes he constructed.
    Anton van Leewenhoek
  34. _?_ reported to the world that life's smallest structural units were "little boxes" or "cells" as he called them.
    Robert Hooke
