Transcript Fire Algae
• • • • 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 •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
