-
-
protoza defined by three characteristics
eukaryotic, unicellular, no cell wall
-
size of protoza
3-300 microns
-
protoza habitats
water, soil, decaying organic matter
-
protoza most are
chemoheterotroph ingesters
-
protoza eat
dead plant/animal, live bacteria/aglae
-
help form the basis of the aquatic foodchain, get eaten by larger animals is a protoza
zooplankton
-
protoza reproduction
all asexual, most also sexual
-
only few are pathogens, but cause 100's of millions infections yearly worldwide
protoza
-
allow host to survive desiccation, nutrient deficiency, lack of O2
cysts
-
allow intestinal protozoa to pass between hosts
cysts
-
all have this stage in the protozoan life cycle
trophozite stage
-
like bacterial endospores but not as resistant
protozoa
-
classify by 18 rRNA and electron microscopy
protozoa
-
Also classified by means of locomotion (motility)
protozoa
-
flowing extensions of cell membrane/in regards to a protozoa
pseudopodia
-
can overgrow in vagina when acidic ph is raised
trichomonas vaginalis
-
is intracellular apicomplexan parasite, can cross placenta and cause spontaneous abortion
toxoplasma
-
causes malaria
plasmodium
-
causes cryptosporidiosis, which is a diarrheal disease
cyrptosporidum
-
causes paralytic shellfish poisoning and makes the powerful toxin called saxtoin
gymnodinium
-
classified by reproduction (spore type) and hyphae type
fungi
-
microscopic, unicellular
yeasts
-
have multicellular tubular filaments
molds
-
reproductive structure of some molds, multicellular
mushrooms, puffballs
-
cell wall is made from chitin
fungi
-
fungi are pathogens and what causes infections in animals
mycoses
-
can cause allegeries by spores in the air
fungi
-
can cause food spoilage
fungi
-
recycle nutrients by feeding off dead plants/animals
decomposers/saprobes
-
Are chemoheterotroph abosorbers
fungi
-
helps with medicine in particular antibiotics penicillin and cephalosporin
fungi
-
long threadlike cells; tubular filaments
hyphae
-
septate hyphae
have crossed cell walls called septum
-
aseptate
no walls, multinucleate
-
-
Vegtative body in mold
thallus/ plural is thalli
-
have reproductive structures made of hyphae
mushrooms/puffballs
-
for yeast are small, globular and single celled
thalli
-
produce both types of thalli depending upon temperature or CO2 concentration
dimorphic
-
separated piece of mycelium can generate new colony
fragmentation
-
yeasts bud and if remain attached can produce
psuedohypha
-
fungal asexual spores have how many types
3
-
produce sporangiospores and spores in SACS
sporangium
-
form inside hyphae
chlamydospore
-
produce conidiospores and free spores
conidia
-
can produce asexually and sexually
fungi
-
fungal sexual reproduction determines
classification
-
only asexual spores found
deuteromycota
-
black bread mold
rhizopus
-
most food spoilage, dutch elm
ascomycota
-
poisonous mushrooms, cellulose decomposers
basidomycoda
-
a ascomycota fungus that provides nutrients,h20, protection from desiccation and harsh light
linchen
-
-
photosynthesis in chloroplasts using chlorophyll
eukarya alage
-
part of phytoplankton which is basis of aquatic foodchain
eukarya alage
-
habitat mostly in fresh and marine waters
eukarya alage
-
eukarya alage reproduction
asexual or sexual
-
cell type is unicellular, colonial, or thalli
eukarya alage
