• Most diverse group
• Eukaryotic cells
• Some autotrophs, some heterotrophs
• Unicellular and multicellular
• Algae-Plant like Protists, autotrophs
• Protozoans-Animal like Protists, all unicellular, heterotrophs
• Fungus like Protists- move at some point in their lives
• Classified by color
• Euglenoids
• Golden Algae
• Green Algae
• Brown Algae
• Red Algae
• Fire Algae
Euglenoids• Autotrophic and heterotrophic• Flagella- hunt like an animal• Chloroplasts- make own food • like plant
Diatoms- two shells
Unicellular and multicellular
Contain chlorophyll
Plant ancestor
Examples: spirogyra, ulva- sea lettuce, volvox- colonial algae
Spirogyra
• Seaweed and kelp
• Has air bladder- gas-filled structures that keep algae floating near the surface for photosynthesis
Feathery and fragile bodies
Live in deep oceans
Dinoflagellates
Bioluminescence- glow
when disturbed in the
water
Red tide- uncontrolled growth (algal bloom) of dinoflagellates. Release poisons that kill fish

AmoebaMove by pseudopodia- “false feet”- extends plasma membrane around prey forming a pocket
Label the parts of the amoeba
• Contractile vacuole- used to pump out excess water

Trypanasoma
Move by flagella
No method of movement
Must live in food supply to survive
Many are parasitic
Slime mold
Plasmodium- colorful slime molds found oozing on rotting logs in forests
