Term
What is the similar characteristic between protistans and eubacteria?
Definition
they have unicellular organisms within them.
Term
Kingdom Eubacteria includes:
Definition
prokaryotic organisms
Term
Kingdom Protista includes:
Definition
eukaryotic organisms
Term
Are Bacteria heterotrophic or autotrophic?
Definition
most are heterotrophic
Term
is cyanobateria heterotrophic or autotrophic?
Definition
autotrophic (photosynthetic)
Term
Name three types of heterotrophic bacteria:
Definition
pathogens, decomposers, nitrogen-fixers
Term
decomposers
Definition
breaking down and recycling of waste products.
Term
Nitrogen-fixers
Definition
capturing the gaseous nitrogen in the atmosphere and making it available to plants via a symbiotic association with their roots.
Term
What are the 3 shapes bacteria exist in?
Definition
coccus, bacillus, and spirillum.
Term
coccus
Definition
sphere
Term
bacillus
Definition
rod-shaped
Term
spirillum
Definition
spiral shaped
Term
Besides shape, what is another way bacteria can be sorted?
Definition
according to how they react to a staining procedure called Gram stain.
Term
Gram positive stains are
Definition
purple
Term
Gram negative stains are
Definition
pink
Term
What are two reasons Gram staining is important to bacteriologists?
Definition
It is one of the first steps in identifying unknown bacteria and the reaction indicates a bacteriums susceptibility or resistance to certain antibiotics.
Term
Which color indicates that the bacterium is suseptible to penicillin?
Definition
purple (Gram-positive)
Term
Another name for cyanobacteria?
Definition
blue0green algae
Term
the three types of symbiosis?
Definition
parasitism, commensalism, mutualism
Term
parasitism
Definition
one organism lives at the expense of the other
Term
commensalism
Definition
occurs when effects are positive for one species and neutral for the other
Term
mutualism
Definition
both organisms benefit from living together
Term
symbiosis
Definition
living together
Term
heterocysts
Definition
cells that are a bit larger than other cells.
Term
thylakoids
Definition
membranes on and in which the photsynthetic pigments are found.
Term
the two types of protistans?
Definition
green(photoautotrophic) and nongreen (heterotrophic)
Term
thylakoids
Definition
membranes on and in which the photsynthetic pigments are found.
Term
What are phylum chytridiomycota?
Definition
a very simple protistan that mostly live on dead matter but some are parasitic.
Term
antheridia
Definition
the male gametotangia
Term
hypha
Definition
the basic unit of a fugal body
Term
mycelium
Definition
all the hyphae constitute this
Term
zoosporangia
Definition
dese tips are cell specialized for asexual reproduction.
Term
monoecious
Definition
both male and female gamettangia are produced on the same mycelium.
Term
dioecious
Definition
organisms producing one type of sex organ on another body.
Term
kingdom
Definition
subdivisions of domains
Term
eubacteria
Definition
domain of all prokaryotic cells except archaebacteria, also called a kingdom.

kingdom of protistans
Term
prokaryotic
Definition
no nucleus or organelles
Term
eukaryotic
Definition
cells having a nucleus and other membrane bound organelles.
Term
ribosomes
Definition
two subunits of rRNA and proteins that breifly join together as a structure on which mRNA is tranlated into polypeptide chains.
Term
heterotrophs
Definition
organism unable to make its own organic compounds.
Term
autotrophs
Definition
any organism that makes its own food with an environmental energy sourse and CO2 as its carbon source.
Term
Pathogens
Definition
Any virus, bacterium, fungus, protistan, or parasitic worm that can infect an organism, multiply in it, and cause disease.
