What are the 3 types of protists?
|
Animal-like
Plant-like Fungus-like |
|
|
The characteristics of the kingdom Protista
|
Eukaryotic
Mostly unicellular (some multicellular) Live primarily in aquatic habitats Both autotrophic & heterotrophic feeders No tissue differentiation |
|
|
Autotroph
|
Organisms that make their own food (producers)
|
|
|
Heterotroph
|
Acquire and ingest food from their surroundings (consumers)
|
|
|
Decomposer
|
Heterotrophs that ingest dead or decaying material. This releases nutrients from dead organisms back into the environment
|
|
|
Cilia
|
hair like projections for locomotion
|
|
|
Flagellum
|
whip like projection for locomotion
|
|
|
Pseudopod
|
false foot created by pushing cytoplasm and extending the cell membrane
|
|
|
What is a contractile vacuole and what is an example?
|
It is a homeostasis to get rid of water in the vacuole to prevent the cell from exploding and paramecium
|
|
|
Zooflagellates
|
flagella used for locomotion and they are what cause African Sleeping Sickness. Transmitted through tsetse fly. (ex. trypanosomes)
|
|
|
Sporozoans
|
causes malaria which is transmitted by mosquito
non motile and many cause disease |
|
|
Plant-like Protist
|
Autotrophs
Unicellular, multicellular, or colonial Lack cell walls so they need water for support Through photosynthesis they produce 80% of all oxygen we breathe (ex. algae, diatoms, seaweed euglena) |
|
|
Fungus - like Protist
|
Decomposer
Cell Walls contain chitin not cellulose water mold caused potato famine many Irish to emigrate to American after 1845 |
