|
1. plasma membrane
2. GA 3. C/F 4. ER 5. mt 6. plastids |
|
|
Describe the 3 body types of protists
|
1. colonial
2. some change(parasitic) 3. encystment |
|
|
What is an encystment?
|
when a protist forms a cyst to stay resistant
|
|
|
How do Protists get nutrients?
|
Can be autotrophic, heterotrophic(holozoic), or osmotrphic(saprozoic)
|
|
|
What is a phagosome?
|
a food vacuole protists create to engulf their food.
|
|
|
What is a cytostome?
|
mouth structure for protists
|
|
|
Cytopyge(cytopropt)
|
Waste expulsion in Protists
|
|
|
How do protists reproduce?
|
asexual: Binary fission, budding
sexual: syngamy, autogamy, conjugation |
|
|
Syngamy
|
nuclei from different individuals fuse(cross)
|
|
|
Autogamy
|
nuclei from same individual fuse(self fert)
|
|
|
Conjugation
|
exchange betweeen two individuals
|
|
|
Is fluid moved parallel to cell surface or cell axis when using a Flagellum to move?
|
Axis. cilia is cell surface
|
|
|
Cirri
|
cilia that have been fused together
|
|
|
Axoneme
|
Extension of the plasma membrane. Has 9 doublets of microtubes with 2 microtubes in the middle(9+2). The kinetosome at the base has a 9+3 arrangement.
|
|
|
Name the types of locomotion/feeding used by protists.
|
Flagella/cilia, axoneme, pseudopod
|
|
|
name the 4 types of pseudopods
|
Lopopodic(wide), Eilipodic(thin), reticulopodic(joined; looks like a horn), and exopodic(MTs inside are shot out to engulf prey quickly)
|
|
|
Explain how the Lobopodia moves
|
ENDOPLASM fountain(sol) moves thru ECTOPLASM(GEL). it pushes the HYLINE CAP outward. the SOL becomes the GEL and it continues
