Flashcards in Chpt 10 - The Protozoans Deck (17):
Unicellular or one-cell organisms or parasites
Flagellates and amoebae
Balantidium coli and Ichthyophthirius multifiliis
Organelles of internal movement, not visible to the naked eye
A long, whiplike or lashlike appendage
Moving or motile form
"False feet" of amoebae
Tiny, short, moving hairs over most of the body surface
Locomotory organelles of apicomplexans and piroplasms
Coccidia, malarial organisms
*Protozoans possessing at least one flagellum in their trophozoite, or moving, form.*
*Protozoans that move via pseudopodia. They have two forms, the motile trophozoite form and the resistant cyst form.*
Name the phyla the parasitic protozoans are categorized in.
What is the most important amebic protozoan in humans?
What protozoan parasites can have beneficial roles for their hosts?
Some ciliate protozoans (such as those in the rumen of the cow or sheep or the cecum of the horse).
How do apicomplexan parasites move?
They move via undulations, as they do not have visible locomotory organelles.
