BIO 203 LCC MUSSER EXAM 1: QUESTIONS WITH
ANSWERS 100% SOLVED
Microbiology - ANSWER The study of microorganisms
Bacteria - ANSWER single-celled organisms that lack a nucleus; prokaryotes
Archaea - ANSWER One of two prokaryotic domains, the other being Bacteria. The
extremists: Live in unlivable conditions
Fungi - ANSWER A eukaryotic organism that has cell walls, uses spores to reproduce,
and is a heterotroph that feeds by absorbing its food.
Protozoa - ANSWER Eukaryotic, unicellular, ingest food from surroundings, can go into
cyst state
Algae - ANSWER Eukaryotic, Autotrophs (Self feeders through photosynthesis)
Helminthe - ANSWER worms, Eukaryotic, multicellular
Virus - ANSWER noncellular, ultimate parasite, no metabolism
Saprophytic - ANSWER Fungi that get their energy from decaying organic matter
Prokaryote - ANSWER no nucleus or membrane bound organelles
Eukaryote - ANSWER A cell that contains a nucleus and membrane bound organelles
, Why study microbiology? - ANSWER microbes have profound impact on our lives and
health
What are the 7 classes of microbes? - ANSWER Bacteria, Archaea,Fungi, Protozoa,
Algae, Helminthe, and Virus
How are the 7 classes of Microbes similar? - ANSWER -All are ubiquitous
-Are either unicellular, multicellular, or cell clusters
-Have means of transport
What is life? - ANSWER composed of cells, metabolism, growth and reproduction
Are all microbes "alive"? - ANSWER No. Viruses are acellular and only thrive within a
host
What is the binomial nomenclature system? - ANSWER Each distinct species is given a
scientific name that is a global standard to avoid confusion
Scientific names consist of _________________ - ANSWER Genus and species
How do you correctly write the name of a microorganism? - ANSWER Genus is always
capitalized and species is always lower case.
Italics if typed, underlined if handwritten
Must be spelled out entirely first time, then can be abbreviated with first letter of Genus
and the entire species
5 kingdom domain system - ANSWER Based on morphology (differences you can see)
