Protists can be defined as singlecelled organisms that contain a
nucleus

Dinoflagellates are plantlike protists
that have two flagella and armor like

Protists

  1. 1. Protists!!!
  2. 2. Protists  Protists can be defined as singlecelled organisms that contain a nucleus
  3. 3. Protists  Protists live in:    Watery environments Moist soil Live inside larger organisms
  4. 4. Protists  Characteristics    Can be autotrophic or heterotrophic Most live as individual cells Some live in large colonies
  5. 5. Protists  3 Major kinds of Protists    Animallike Plantlike Funguslike
  6. 6. Protists  The animallike protists are broken down into 4 major groups     Sarcodines Ciliates Zooflagellates Sporozoans
  7. 7. Sarcodines  Sarcodines can be identified by their pseudopods or “false-foot”    Pseudopod is a footlike extension that an amoeba uses to move and capture food Ex. Amoeba (NNN) VIDEO!!!
  8. 8. Ciliates  Ciliates have small hairlike projections on the outside of their cells    Cilia act like tiny oars to move the organism Ex. Paramecium Stentor, Spirostomum
  9. 9. Zooflagellates  Zooflagellates are animallike protists that move using a flagella (usually 1-8 flagella)!   Many kinds live inside other organisms as symbionts a few are parasites Ex. Giardia
  10. 10. Sporozoans   All sporozoans are parasites that feed on the cells and body fluids of their host animals Ex. Plasmodium malaria
  11. 11. Plantlike Protists  Plantlike protists capture energy from the sun using chloroplasts
  12. 12. Plantlike Protists  Three major groups of plantlike protists    Euglenas Diatoms Dinoflagellates (WHICH IS WHICH????)
  13. 13. Euglena  All possess two flagella, eyespots (why?!), and green structures used in photosynthesis
  14. 14. Diatoms  Diatoms are plantlike protists made of a tough glasslike, silicon material
  15. 15. Dinoflagellates  Dinoflagellates are plantlike protists that have two flagella and armor like cell walls
  16. 16. Fungus-like Protists  Fungus-like protists are heterotrophic, have cell walls, and use spores to reproduce. An example are slime molds.
