1. Protists
Domain: Eukarya
Kingdom: Protista

2. Protists are:
Single-celled (unicellular) or simple multicellular, microscopic,
eukaryotic (with a nucleus) organisms

3. (Phytoflagellates): Autotrophs (self- nourished)
Producers - produce their own food from light.

4. Algae Green Algae (7500sp) Red Algae (5000sp) Used in making ice cream
Brown Algae (1500sp)

5. Euglena Flagellum Eyespot Chloroplasts
Uses its eyespot to sense sunlight
Moves by 2 flagella (1 short and 1 long)
Contains chloroplasts to produce food for itself
Eyespot
Chloroplasts

6. Diatoms Colorful - Many Shapes Phytoplankton
Used to make toothpaste, insecticides and dynamite

7. Dinoflagellates (whirling-whip)
2 Flagella; Cell Wall
Red Tide

8. Heterotrophs (other-nourished) that MOVE
Protozoans
Protists that move, but cannot make their own food

9. Sarcodines Pseudopods -extensions of the cell membrane and cytoplasm
Engulf food particles
Assist with movement
Amoeba
Radiolarian

10. Ciliates
Have small, hair-like projections called cilia on the outside of their bodies
Provide movement
Act as sensors
Can help sweep in food
Paramecium

11. Zooflagellates Protists that move using a flagellum
Live in water or within other organisms
Symbiotic relationship: Termites and wood roaches rely on a type of zooflagellate to digest the wood

12. Heterotrophs that can’t move
Slime Molds – Cause of the great potato famine in Ireland; reproduce by spores
Sporozoans – parasites that feed on cells and body fluids of their host animal
Reproduce by producing spores
