Protists Powerpoint
- 2. 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
- 3. 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
- 4. 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
- 5. 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
- 6. 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
- 7. 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
- 8. 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/
- 9. 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
- 10. 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
- 11. Unicellular Uses cilia to move and capture prey Common in freshwater lakes and streams Ciliophora Stentor roeseli http://en.wikipedia.org/wiki/Stentor_(protozoa)
- 12. 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
- 13. 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
- 14. 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/
- 15. Lives in the gut of termites to help them digest wood Has 4 anterior flagella Unicellular Metamonada Mixotricha paradoxa http://en.wikipedia.org/wiki/Mixotricha_paradoxa http://microbewiki.kenyon.edu/index.php/Mixotricha
- 16. Phyla Apicomplexa Single celled Can cause diarrhea Only uses human hosts Cyclospora cayetanensis http://en.wikipedia.org/wiki/Cyclospora_cayetanensis
