|
|
photosynthetic, plant-like protists
|
algae

|
flagellates
|
|
type of reproduction where a single parent produces offspring identical to itself
|
asexual reproduction
|
|
extension of the plasma membrane, containing cytoplasm, used by certain protozoans to move and feed
|
pseudopodia
|
|
Name the four major groups of protozoans
|
flagellates, ciliates, amoeba, and sporozoans
|
|
All protozoans are (heterotrophs or autotrophs)?
|
heterotrophs
|
|
What are the three types of protists?
|
Animal-like protists (protozoans), plant-like protists (algae), and fungi-like protists
|
|
How are protozoans different from animals?
|
Protozoans are all unicellular; animals are all multicellular
|
|
How are plant-like protists different from plants?
|
Algae have no roots, stems, or leaves
|
|
How are the fungi-like protists different from fungi?
|
They are able to move at some point in their life and they don't have chitin in their cell walls
|
|
How are sporozoans different from other protozoan groups?
|
They reproduce using spores and they are parasites.
|
|
How do contractile vacuoles help freshwater protozoans maintain homeostasis?
|
Freshwater protozoans live in a hypotonic environment so water is constantly entering the cell. The contractile vacuoles pump out excess water so they don't burst.
|
|
How do amoeba obtain food?
|
They form pseudopodia that reach out and surround the food.
|
|
How are ciliates and flagellates different?
|
Ciliates move using many tiny cilia which move together like oars. Flagellates have one or a few longer whip-like flagella.
