VERIFIED ANSWERS / EXAM QUESTIONS WILL COME
FROM HERE (100% CORRECT ANSWERS/ A+ GRADED




Microbe - ANSWERS--Acellular or cellular objects that cannot typically
be visualized with the naked eye


Virus - ANSWERS--Acellular microbe made of proteins and DNA or RNA,
uses certain types of host cells to reproduce and develop infectious
characteristics


Prion - ANSWERS--Acellular microbe made of a misfolded protein, can
become infectious depending on the misfolding causing other proteins
to misfold and become infectious prions as well


Bacteria - ANSWERS--Unicellular microbes considered prokaryotic, have
no nucleus or membrane bound organelles ex) e. coli


Archaea - ANSWERS--Unicellular microbes considered prokaryotic but
differentiated at a later point from eukaryotic cell development from
eubacteria, have no nucleus or membrane bound organelles ex)
thermus aquaticus

Algae - ANSWERS--Unicellular colonial microbes considered eukaryotic
protists, have nucleus and membrane bound organelles ex) Protafeca


Protozoa - ANSWERS--Unicellular microbes considered transitional
eukaryotic protists, have varying development of membrane bound
organelles ex) giardia


Yeast - ANSWERS--Unicellular microbes considered eukaryotic fungi,
have nucleus and membrane bound organelles


Molds - ANSWERS--Uni/multicellular microbes considered eukaryotic
fungi, have nucleus and membrane bound organelles


5 Kingdom system (outdated) - ANSWERS--1) Monera - bacteria,
archaea
2) Protista - Protozoa, algae
3) Fungi - Yeast, mold, mushroom
4) Plantae - Trees and shit
5) Animalia - Dogs and shit


3 Domains system (more accurate) - ANSWERS--1) Bacteria

Naming/classifying bacteria, fungi, and protozoa - ANSWERS--Genus,
species, strain ex) Escheria coli 15H7 (underlined)


Magnification= - ANSWERS--Objective x Eyepiece


Resolving power - ANSWERS--Ability of lens to distinguish between
objects close together


Light microscopy - ANSWERS--Resolution power of .2 um, can see
eukaryotes and prokaryotes but not viruses


4 types of light microscopy - ANSWERS--1) Bright field - Must heat fix
(kill) and stain first, background light, bacteria appear as color of stain
2) Dark field - Light refracted by organism, background dark, organism
bright
3) Phase contrast - converts slight differences in refractive indices to be
easily detected variables
4) Fluorescence - Uses UV light to excite fluorescent molecules such as
GFP or fluorochime labelled antibodies


Electron microscopy - ANSWERS--Resolution 1000x better than light
microscope - .0005 um resolution

Basic dyes - ANSWERS--Bind to negatively charged structures


Acidic dyes - ANSWERS--Bind to positively charged structures


Differential stains - ANSWERS--Divide microbes into caegories
depending on structural characteristics


Gram stains - ANSWERS--Separate bacteria based on type of cell wall (+
or - charge)


Gram positive stain - ANSWERS--Indicates a thick cell wall


Gram negative stain - ANSWERS--Indicates a thin cell wall


Acid fast stain - ANSWERS--Type of differential stain that identifies
bacteria neither pos. or neg. that have thick waxy mycolic acid layer
around them, have to use heat to get stain to stick


Steps in an acid fast stain - ANSWERS--1) Addition of carbol fushia
2) Heating of slide
3) Acid alcohol wash
4) Counterstain
