GENERAL PROTISTS
What type of cell do all protists have: prokaryotic or eukaryotic?
Eukaryotic cells.
What type of nutrition do algae have?
Autotrophic (photosynthetic).
What is fragmentation?
Asexual reproduction where part of the alga grows into a new individual.
Where do green algae live?
In fresh water or the sea.
Are protozoans autotrophic or heterotrophic?
Heterotrophic
Do multicellular protists have differentiated tissues?
No, all their cells are similar except reproductive cells.
What organelle in algae allows photosynthesis to occur?
Chloroplasts.
What are spores in algae?
Special cells that grow into new organisms.
Which algae are the largest in the world?
Brown algae.
What three methods do protozoans use for movement?
Cilia, flagella, and pseudopods.
Name the two major groups of protists.
Algae and protozoans.
Do all algae have cell walls?
Most do, but some unicellular algae may not.
How do unicellular algae usually respond to environmental stimuli like light?
By moving toward or away from the stimulus.
Are red algae usually unicellular or multicellular?
Multicellular.
Which group includes amoebas?
Rhizopods
Are protists usually unicellular, multicellular, or both?
Both
Can unicellular algae move?
Yes, many can move; some even creep.
How do multicellular algae respond to light?
By increasing in size.
Which type of algae rarely live in fresh water?
Red algae.
Which group cannot move and includes Plasmodium?
Sporozoans
What is the main difference between algae and protozoans?
Algae are autotrophs; protozoans are heterotrophs.
Why might algae appear red, brown, or yellow instead of green?
Other pigments can mask the green chlorophyll.
Name one type of algae that reproduces by fragmentation.
Caulerpa prolifera
Which type(s) can be both unicellular and multicellular: green, red, or brown algae?
Green algae.
What disease is caused by Trypanosoma and spread by the tsetse fly?
Sleeping sickness
