Protists Flashcards
Types
Excavata
Rhizaria
Alveolata
Amoebozoa
Excavata
Both chemoorganotrophs-mitochondria +phototrophs-Chlorplasts
both symbiotes+parasites
Kinetoplastids-Kill
contain a kinetoplast-mass of DNA in their mitochondria-no undulating membrane
aquatic habitat-feed on bacteria-free-living
single flagellum
Ex: Trypanosoma brucei-African sleeping sickness-lives and grows in blood stream,digest blood cells,neurological symptoms
Diplomonads-dumb
2 nuclei of equal size
Multiple flagella (2 or 4)
small genomes +parasites
Ex:Giardia lambila-found in feces contaminated water,giardiasis,waterborne diarrheal diseases
Parabasalids-protists
contain a parabasal body-swim/steer
moves with undulating membrane +flagella
live in intestinal and urinary tract-parasites+commensal symbiote-digest food+break down.
Ex: Trichomonas vaginalis-STD-males and females,motile via flagella
Euglenids-Ella
Chemotrophic +phototrophic
Two flagella-one steers,propeller
feed on bacteria in water
Ex: Euglena gracilis-freshwater,no harm to us, produces protein-rich flour, feeds on bacteria
Alveolata
Alveoli
cytoplasmic sacs located under the cytoplasmic membrane
Osmotic balance
Armor
Ciliates-Cal
possesses cilia-motility-swim like inchworms
two kinds of nuclei-micronuclei+marconuclei
help +harm
Ex: Paramecium-Cilia to obtain food+mobility,Oral groove-move material down to gullet
anal pore-poop
Phagotysis
Dinoflagellates-dyed
Marine +freshwater
Phototrophic
two flagella of different length-one wrap around,one bottom
free-living +symbiotic
Ex: Gonyaulax-toxic and “red tides”,fish-killing,paralytic shellfish poisoning
Bioluminescent-feel vibrations,light up to attract second predator
Apicomplexans-arota
Parasites
non-motile
Ex:Malaria-plasmodium,toxoplasmosis-toxoplasma,cocidiosis-eimeria
Rhizaria
Threadlike cytoplasmic extrusions
Psudopodia
move+feed
Chlorarachniophyta-cal
freshwater+marine
Flagellum
Cyanobacteria-chloroplasts with 2 membranes
Chlorarachniphytes-chloroplasts with 4 membranes
Foraminifera-Fucked
Only ocean
shell-like structures called tests-solid,many shapes,live on bottom
tests=sink,not firmly attached,holes extend to eat
can’t swim
made of calcium carbonate
Radiolaria-Riley
Planktonic eukaryotes
cosume bacteria+organic matter
Tests=more holes
mineral skeletons made of silica
needle-like pseudopodia keeps from sinking
swim araound
Amoeboza
moist areas+aquatic
lobe-shaped pseudopodia for feeding movement
