Transcript

  • 1. By Steven Campbell
  • 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

    • 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
