Protists

  1. 1. ProtistsMolly, Annie, Shannon, Gabrielle,Emily
  2. 2. Phylogenetic Tree for Kingdoms I <3 Protists
  3. 3. What does this mean ?As you can see, Protists are under theEukaryotes section on the right of thatgraph. That means they are more closelyrelated to animals, plants, and fungi thenthey are to chloroplast and mitochondria. OH I get it
  4. 4. DISTINCTIONS from otherkingdoms● Protists have simple organization. Either they are unicellular, or theyre multicellular without specialized tissues.● Protists, as previously stated, are eukaryotes. Bacteria, however, is prokaryotic.● They have a true nucleus● Fascinating!
  5. 5. What makes a protist a protist?Protists are...● Eukaryotic organisms● Live in almost any area with liquid water● Are autotrophs or organotrophs (by absorption or ingestion)● Can reproduce sexually (gametic) or asexually (binary fission)● Can be pathogens for animals or plants; e.g. malaria Protists rock!!● Produce oxygen
  6. 6. How do they move?● Cilia- microscopic "hairs" that extend from the protist that act in unison to move the organism.● Flagella- A long appendage (like a whip) that moves the organism. It can be a single or double appendage.● Pseudopodia- A temporary projection of the cytoplasm (amoebas often move this way) Soooo locomotive
  7. 7. Ecology● Found in ponds, on trees, or other natural aquatic ecosystems● Fossilized protists have been found from the Precambrian era (1.9 bya)● Some symbiotic protists live with fungi or other plants WOWZA
  8. 8. WOAH lookat all thoselittle guys!
  9. 9. Lets review!! WOO Recap:Protist move using cilia, flagella, pseudopodia.Found in habitats where water is also found.Some are single cellular, some are multicellular.Some are autotrophs some are heterotrophs.Protists eat other protozoa, amoeba and algae.
