Chapter 1: History of Microbiology Flashcards
Antoni Van Leewenhoek
made and used simple microscopes to observe microorganisms
-father of microbiology
Carolus Linnaeus
developed a taxonomic system that helped name plants/animals and helped group similar organisms together
taxonomy
system of naming and grouping
eukaryotes
have membrane-bound nucleus
What are the six categories of microbes?
bacteria, archaea, fungi, protozoa, algae, small multicellular animals
bacteria and archaea
unicellular
no nuclei
thrive in moisture
asexual reproduction
smaller than eukaryotes
fungi
eukaryotic
have cell walls
molds and yeasts are examples
obtain food from other organisms or saprophytic
protozoa
single-celled eukaryotes
mostly asexual
most can perform locomotion
algae
unicellular or multicellular
photosynthetic
simple reproductive structures
Why is Leeuwenhoek the father of microbiology?
he made and used simple microscopes to examine microorganisms
abiogenesis
spontaneous generation
What were the four questions posed during the Golden Age?
Is spontaneous generation possible?
What causes fermentation?
What causes disease?
How can we prevent infection and disease?
What was Aristotle’s approach to spontaneous generation?
living things arise from from nonliving matter
What was Needhams’s approach to spontaneous generation?
large animals could not arise spontaneously but microbes could
What was created as a result of all of the spontaneous generation experiments?
scientific method
1. Ask a question
2. Hypothesis
3. Experiment
4. Analyze
5. Conclusion
pasteurization
process of heating liquids just enough to kill most bacteria
What did Buchner reveal about fermentation?
does not require living cells
