group of parasitic protozoans that reproduce by spore production
haploid reproductive cell with a hard outer coat that forms a new organisim without fertilization
group of protozoans that use cilia to move
unicellular, animal-like protist
photosynthetic, plant-like protists
protists that use one or more flagella to move
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
Name the four major groups of protozoans
flagellates, ciliates, amoeba, and sporozoans
All protozoans are (heterotrophs or autotrophs)?
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.
