• 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

More Diatoms

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
