Causes African sleeping sickness Unicellular Single flagella Some Euglenozoans have chloroplasts Do not have a cell wall Trypanosoma brucei http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/P/Protists.html
Single celled Lives in freshwater, saltwater,
soil, and even as parasites. Sarcodina Reproduces asexually Moves via pseudopods, and
also consumes other organisms (like protists) with pseudopods
Amoeba proteus http://www.scienceclarified.com/Al-As/
Amoeba.html
Single celled Move via cilia (is a ciliate) Eats via a gullet, and feeds on
microorganisms like yeast and bacteria
Can be found in freshwater rivers, lakes, and ponds
Ciliophora Paramecium aurelia http://www.bio.umass.edu/biology/conn.river/
parameci.html
Known to cause malaria Apicomplexa Single-celled Lives in the saliva of
mosquitoes and as a host in humans and other animals
Is a parasite and requires a host to live
Plasmodium falciparum http://en.wikipedia.org/wiki/Plasmodium
Unicellular Contains chloroplasts Lives in a marine habitat Can reproduce
“explosively” to cause red tides and kill mass amounts of fish
Moves by multiple, irregular flagella
Ceratium hirundinella http://en.wikipedia.org/wiki/Dinoflagellate
Unicellular Found in freshwater Responsible for most
freshwater photosynthesis – are the main producers
Heterokontophyta Arachnoidiscus ehrenbergi http://users.rcn.com/jkimball.ma.ultranet/
BiologyPages/P/Protists.html
Contain golden-brown chloroplasts
Have two dissimilar flagella Lives in cold fresh water Heterokontophyta Causes foul-tasting water
occasionally Unicellular Prymnesium parvum http://www.cs.cuc.edu/~tfutcher/
Chrysophyta.html http://www.tpwd.state.tx.us/landwater/water/
environconcerns/hab/ga/
Multicellular Has cell walls made of
cellulose Is a fish parasite and can
cause economic damage to fish hatcheries
Has hyphae Heterkonta Saprolegnia parasitica http://botit.botany.wisc.edu/toms_fungi/
saprolegnia.html http://en.wikipedia.org/wiki/Saprolegnia
Lives in the ocean Uses the pigment
phycoerythrin, which allows it to dwell in deeper areas
Important source of food in Asia
Multicellular Autotrophic Rhodophyta Kallymenia perforata http://www.ucmp.berkeley.edu/protista/
rhodophyta.html http://www.tolweb.org/Rhodophyta
Unicellular Uses cilia to move and
capture prey Common in freshwater
lakes and streams Ciliophora Stentor roeseli http://en.wikipedia.org/wiki/
Stentor_(protozoa)
Reproduce by budding Unicellular Usually anchored to
something, although they can be free-swimming via cilia
Uses a myoneme to coil up like a spring
Ciliophora Vorticella convallaria http://www.microscope-microscope.org/
applications/pond-critters/protozoans/ciliphora/vorticella.htm
Technically unicellular, but have lots of nuclei and are formed when many flagellates fuse
Move by streaming cytoplasm, similar to amoebas but on a larger scale.
Lives in cool, moist, shady areas like dead leaves and logs
Amoebozoa Physarum polycephalum http://www.ucmp.berkeley.edu/protista/
slimemolds.html
1 flagella Single-celled Euglenozoa Has a distinct eyespot
or stigma that reacts to light
Lives in marine and fresh water
Euglena gracilis http://euglena.msu.edu/
Lives in the gut of termites to help them digest wood
Has 4 anterior flagella Unicellular Metamonada Mixotricha paradoxa http://en.wikipedia.org/wiki/

Phyla Apicomplexa Single celled Can cause diarrhea Only uses human hosts Cyclospora cayetanensis http://en.wikipedia.org/wiki/
