|
what are the three metabolisms of protists
|
photosynthesis
heterotrophy parasites |
|
|
Protozoans
|
means heterotrophic protists (protists that move and eat other things for food) animal like protists
includes paramecium and amoeba |
|
|
what are protozoans also called
|
zooplankton
|
|
|
why are zooplankton not always protozoans
|
they are sometimes photosynthetic
|
|
|
phytoplankton
|
photosynthetic protists
|
|
|
what are three examples of algae (lap)
|
diatoms spirogyra volvox
|
|
|
what is the multicellular form of algae
|
seaweed and kelp
|
|
|
Sarcodina
|
Amoeba
moves with psudapodia engulfs prey with phagocytosis (encloses it with its cytoplasm) Has a contractile vacuole to pump out excess water hard shell made of carbonie, calcium, and silica |
|
|
Ciliophora
|
Paramecium and Stentor
moves with cilia LARGEST group most are freshwater, some are marine often have TWO nuclei and trade DNA through conjugation have contractile vacuoles eat with oral groobs |
|
|
Zoomastigina
|
Trypanosoma, Giardia, Trichomympha
Trypanosoma- African sleeping sickness Giardia- Mr Reeds Dad Trichomympha- Gut of Termintes move with flagella often are marine |
|
|
sporozoa
|
plasmodium
plasmodium causes malaria don't move- no movement most are PARASITIC!!!! make spores plasmodium travel to your liver than go attack ur blood (malaria) |
|
|
what are three characteristics that ALL protozoa have
|
1) heterotrophic
2) Eukaryotic 3) Classified by movement |
|
|
what are four characteristics that classify algae
|
color
type of chlorophyll form of food storage (glycogen?startch?) cell wall composition |
|
|
all algae have at least chlorophyll __
|
A
|
|
|
chlorophyta
|
spirogyra, volvox, olva (sea lettuce), lichen
aka Green Algae LIchen- 2 organisms that live symbiotically with eachother Chlorophyta are ancestors to modern day plants |
|
|
Phaeophyta
|
Fucas and Nori (seaweed on sushi)
LARGEST of all protists IN SIZE have air bladders that help them stay afloat so they can do photosynthesis aka brown algae |
|
|
Rhodophyta
|
live in the med. sea and Caribbean sea (warm water)
Red Algae Used to make AGAR |
|
|
Bacillariophyta
|
aka Diatoms
glass like SHELLS-- SHARP used to make detergents, cleaning stuff, toothpaste, braces geometrically shaped |
|
|
contractile vacuoles
|
pumps excess water out of the protist
|
|
|
how do paramecium eat
|
uses cilia to sweep food into its oral groob
|
|
|
phagocytosis
|
amoeba uses phagocytosis to eat
its a form of endocytosis (encloses the prey using cytoplasm) |
|
|
how do amoeba move
|
it pushes out some of its cytoplasm and moves the rest into the space (it inches like a slug)
|
|
|
pseudopod
|
helps certain protists move
|
|
|
what is the function of the eyespot
|
it helps the euglena detect where it is sunny so it can go towards it and do photosythesis
|
|
|
what is special about euglena
|
its heterotrophic during the nite and photosynthetic during the day-- its both plant and animal like
|
|
|
mixotroph and an example of a mixotroph
|
does photosynthesis and heterotrophy
euglena is an example |
|
|
colonial protists (and example)
|
VOLVOX
protists that live and group together-- but they can live by themselves if needed |
|
|
how are protozoans (not protists protozoans know the dif) classified
|
by movement
|
|
|
which would be more likely to be free living a motile or nonmotile protozoan
|
a motile protazoan b/c motile protozoans aren't parasidic and can feed themselves unlike nonmotile ones
|
|
|
how does the movement method of amoeba help with digestion
|
when the cytoplasm moves it pushes food vacuoles which helps with digestion
|
|
|
pseudopodia
|
used for movement
|
|
|
what are the three ways of movement in protozoans
|
pseudopodia flagella and cilia
|
|
|
what protist is trumpet like
|
stentor (goldfish)
|
|
|
what are the two techniques of reproduction used by protists
|
asexual
meiosis and fertilization |
|
|
what do most protists have in their cell walls
|
calcium and carbonite
|
|
|
all ___ are __ but not all ___ are___
|
all zooplankton are protozoans but not all protozoans are zooplankton
|
|
|
what group of protozoans make up the white chalky stuff on the white cliffs of dover
|
sarcodina
the white cliffs of dover are white b/c of the dead old amoeba on the cliff |
|
|
what group of protozoans is the largest group (in variety not size)
|
ciliophora
|
|
|
ciliophora live in the water so___
|
they have contractile vacuoles
|
|
|
what two groups of protozoans are parasidic
|
zoomastigina and sporozoa
|
|
|
what group of protozoan don't move
|
sporozoa
|
|
|
what two things are psudopods used for
|
phagocytosis and movement
|
|
|
what two things live symbiotically with eachother called Lichen

what type of cholorophyll, cell wall structure, and food storage method does chloropyta have
|
chlorophyll A and B
Startch Cellulose |
|
|

they form cysts in order to survive the winter |
|
|
Euglenophyta
|
Euglenoids- Euglena
Mixotrophs (photosynthetic and heterotrophic) often don't have a cell wall-- instead they have a pellicle pellicle (protein coat that euglenophyta have instead of a cell wall) they have an eyespot |
