protist Flashcards
Protist generality
eukaryotes, most are unicellular and aquatic, very diverse, can be animal like, plant like or protist like
types of nutrition protists
photoautrophs: photosynthesis
chemotrophes:
absorptive: absorb monomes
ingestive: ingest food, then digest it
mixotroph: alternate between both
Movement protist
amoeboid motion (via pseudopodia): cyroplasmic streaming moves cytoplasm
Swimming via cilia or flagella
desmids
two symmetrical half cells
type of green algae
phytoplankton
non motile
contains cell wall
photoautrophs
store energy with starch
plant like
volvox
big ball with smaller balls
type of green algae
phytoplankton
flagella
contains cell wall
photoautrophs
store energy with starch
colonial
eyespot, positive phototaxis
plant like
diatoms
little blue/transparent shapes
algae
non motile
contains cell wall
photoautrophs
store energy with oil
do a lot of O2
plant like
euglena
little green boy
flagella
mixotrophs, photo contribute to phytoplankton, chemo contribute to zooplankton
eyespot
plantlike
amoeba
big translucent boy
protoza (animal like)
zooplankton
pseudopodia
chemotrophs, ingest through food vacuole
contractile vacuole
ciliates
zooplankton
mutualists
cilia
chemotrophs, ingest through oral groove
contractile vacuole
animal like
trypanosomes
flagella
protoza
sickness
utility or protist
produce oxygen
basis of aquatic food webs (primary production: are eaten by others)
symbiosis mutualism or parasitism
phytoplankton vs zooplankton
phytoplankton :photosynthetic plankton
zooplankton: non-photosynthetic plankton
