• • 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

• Classified by method of movement • Rhizopods • Ciliates • Flagellates Flagellate • Sporozoans

Move by pseudopodia - “false feet”- extends plasma membrane around prey forming a pocket Amoeba

Label the parts of the amoeba • Contractile vacuole- used to pump out excess water Nucleus Plasma membrane Contractile vacuole Food particle engulfed by pseudopodia Food vacuole Pseudopodia cytoplasm

Move by beating cilia Paramecium Stentor

Cilia Anal pore Contractile Vacuole Oral groove micronucleus macronucleus

Move by flagella Trypanasoma

No method of movement Must live in food supply to survive Many are parasitic

Plasmodium- colorful slime molds found oozing on rotting logs in forests Slime mold

• Classified by the shape of the structure that holds the spores • Saprophytes- feed on dead matter • Some parasites • Stationary like plants/Heterotrophic like animals • Absorb food through cell walls

Bread Mold-Rhizopus Sporangia Black Mold -Stachybotris

Rhizopus- Bread Mold spores sporangium sporangiophore Hyphae mycellium

gills cap button stipe basidia spores

important in brewing and baking, make Penicillium

Fungus and algae Mutualistic relationship-algae provides food and fungus provides protection and moisture
