1,2,3,7) UPDATED ACTUAL Exam
Questions and CORRECT Answers
Microbiology - CORRECT ANSWER - The study of microscopic organisms. Have
ubiquitous nature (everywhere), some beneficial, some neutral, some pathogenic (disease-
causing)
Antoine van Leeuwenhoek - CORRECT ANSWER - Father of microbiology. Invented a
microscope strong enough to view microbes "animalcules".
Giralamo Fracastoro - CORRECT ANSWER - Regarded as first person to formally
postulate that disease was spread by tiny invisible seminaria "seeds of contagion".
Robert Hooke - CORRECT ANSWER - First to observe cells.
Louis Pasteur - CORRECT ANSWER - A French chemist, this man discovered that heat
could kill bacteria that otherwise spoiled liquids including milk, wine, and beer. Showed that
microbial strains were unique, performed fermentation, and began the development of
pasteurization and vaccines.
Robert Koch - CORRECT ANSWER - Developed the culture plate method to identify
pathogens. First to connect microbe with a specific disease. Discovered causative agent for
anthrax, cholera, and tuberculosis.
Taxonomy - CORRECT ANSWER - The scientific study of how living things are
classified
Carolus Linneaus - CORRECT ANSWER - The "Father of Taxonomy". He came up with
our modern day system of classification called Binomial Nomenclature. Most famous early
taxonomists. Divided 3 kingdoms animal, plant, and mineral. Sublevels: kingdom, class, order,
family, genus, species
, Phylogeny - CORRECT ANSWER - The evolutionary history of a species or group of
related species.
Ernst Haeckel - CORRECT ANSWER - Father of ecology. Proposed another kingdom,
protista, later monera.
Robert Whittaker - CORRECT ANSWER - added fungi as a 5th kingdom of eukaryotic
microbes. Divided kingdoms into prokaryote (monera) and eukaryote (fungi, protista, plantae,
animalia)
Carl Woese and George Fox - CORRECT ANSWER - Studied the small subunit of the
ribosome
Proposed a separate taxonomic unit: Archaea.
Also proposed a new taxonomic system representing three domains: bacteria, archaea, and
eukarya.
Binomial nomenclature - CORRECT ANSWER - Classification system in which each
species is assigned a two-part scientific name. (Written in italics, Genus is capitalized, species
lower case)
Bergey's Manual of Bacteriology - CORRECT ANSWER - Manual for identifying and
classifying microorganisms via non-visual characteristics.
Taxonomy order - CORRECT ANSWER - Domain, Kingdom, Phylum, Class, Order,
Family, Genus, Species.
(T/F) within 1 species of a microorganism, there can be several subtypes called strains. -
CORRECT ANSWER - True, can be nearly identical genetically. Every strain varies in
ability to cause disease.
