1. Protists

2. What is a Protist? All single celled eukaryotes.
Most diverse group of organisms.
Can be plant, animal, or fungus like.

3. Protozoans: Animal Like Protists
Unicellular heterotrophs
Feed on other organisms or dead organic matter.
Usually reproduce sexually, but some produce asexually.

4. Locomotion Some use cilia Some use flagella Others use pseudopods
An extension of the cytoplasm that allow cells to move.

5. Amoebas Move using pseudopods. Can be found in fresh or salt water.
Most reproduce by asexual reproduction.

6. Flagellates Use flagella for locomotion.
Can cause diseases in animals such as African sleeping sickness.
Others are beneficial, helping some animals with digestion.

7. Ciliates Used cilia to move. Live in every type of aquatic habitat.
Most common example is a paramecium

9. Sporozoans Parasitic protozoans Reproduce using spores
One member of this Phylum is plasmodium, the cause of malaria.

10. Algae: Plant Like Protists
All contain chlorophyll
Single celled organisms known as photoplankton.
Responsible for much of the oxygen in the world

11. Euglenoids Autotrophs and heterotrophs
Can do photosynthesis but also ingest food if light is not available.
Can move with flagella.

12. Diatoms: Golden Algae Contain chlorophyll and carotenoids
Carotenoids give them their yellow color.
Store food as oil instead of fat which allows them to float.
Reproduce asexually until they are too small.

13. Dinoflagellates Come in a great variety of shapes Have 2 flagella
Contain chlorophyll, carotenoids and red pigments
Can produce toxins that have been responsible for fish kill off the coast of NC

14. Fungus Like Protists: Slime Molds
Huge groups of protists living together.
Can be plasmodial or cellular.
Plasmodial: No cell walls or membranes, just many nuclei in one cytoplasm.
Cellular: Individual cells live on their own until food is scarce, then join hundreds of thousands of others to reproduce.
