MICROBIOLOGY 2117 TEST 1 EXAM QUESTIONS AND ANSWERS
taxonomic system - CORRECT ANSWER✅✅a system for naming plants and animals and grouping similar
organisms together
Scientists no longer classify yeasts, molds, and mushrooms as plants but instead as fungi - CORRECT
ANSWER✅✅true
prokaryotic - CORRECT ANSWER✅✅lack nuclei
DNA found on the chromosome or chromosome in the cytoplasm
no membraneous organelles
e.g - bacteria/archae
not surrounded by a membrane
bacteria cell walls are composed of - CORRECT ANSWER✅✅polysaccharide called peptidoglycan
eurokaryotic - CORRECT ANSWER✅✅has a nucleus
has a membrane
A - Animal cells
P - plant cells
F - fungi
P - protozoa
fungi - CORRECT ANSWER✅✅single cell yeast
multicell molds
has a cell wall
,obtain food from other organisms
molds - CORRECT ANSWER✅✅multicellular organisms
grow as long filaments
reproduces by sexual and asexual spores
Penicilian chrysogenum - CORRECT ANSWER✅✅a mold that produce penicillin
yeast - CORRECT ANSWER✅✅unicellular
oval to round

mycoses - CORRECT ANSWER✅✅fungal disease
, helminths - CORRECT ANSWER✅✅worms
(tapeworms, flukes, roundworms)
three doman system - CORRECT ANSWER✅✅BAE
Bacteria
Archaea
Eukarya
taxonomic scheme is further categorized into - CORRECT ANSWER✅✅pcofgs
phylum (large group of related animals and plants)
class
order
family
genus
species
viruses - CORRECT ANSWER✅✅acellular (no cell)
colony - CORRECT ANSWER✅✅several individual organisms living together on close association
what do you use to obtain single colonies of bacteria - CORRECT ANSWER✅✅streak plates
difference between a colony and the culture - CORRECT ANSWER✅✅colony - isolated group of
microorganisms grown in a surface
culture - can be solid (agar) or liquid (broth) we used to grow microorganisms...it's the medium
