Microbiology Basics Quiz

The study of microscopic organisms, microbes

Too small to see without a microscope

Living microorganisms with cells; e.g., bacteria, fungi, protists

Unicellular prokaryotes, lack a nucleus, have a peptidoglycan cell wall; reproduce by binary fission

Prokaryotic microbes, different cell wall structure than bacteria; live in extreme environments

Eukaryotic cells; typically multicellular (e.g., mushrooms); chitin cell walls

Unicellular aerobic eukaryotes

Eukaryotic, unicellular or multicellular; obtain food via photosynthesis

Non-cellular infectious agents, e.g., viruses, prions, viroids

Noncellular entities with nucleic acid core (DNA/RNA) & protein coat; depend on host for reproduction

Include helminths, which are worms

Difference in cell structure; prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Flatworms and roundworms; not microorganisms, but microscopic life cycles.

Study of organisms in Bacteria and Archaea domains.

Study of fungi; includes molds, yeasts, and mushrooms.

Study of parasites; includes protozoa and helminths.

Study of viruses; including their characteristics and diseases.

Study of the body's defense system against infection, including serology.

Classification, naming, and identification of microorganisms.

Using biological systems or processes to create products.

Altering the genetic makeup of organisms to create desired products.

Broadest categories of living organisms - Bacteria, Archaea, and Eukarya.

A domain of prokaryotic organisms.

A domain of prokaryotic organisms, often found in extreme environments.

The domain of eukaryotic organisms; includes fungi, plants, and animals.
