Protists and Fungi

Characteristics of Kingdom Protista Most diverse group Eukaryotic cells Some autotrophs, some heterotrophs Unicellular and multicellular

Kingdom Protista Types Algae-Plant like Protists, autotrophs Protozoans-Animal like Protists, all unicellular, heterotrophs Fungus like Protists- move at some point in their lives

Algae 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

Golden Algae Diatoms- two shells

More Diatoms

Green Algae Unicellular and multicellular Contain chlorophyll Plant ancestor Examples: spirogyra, ulva- sea lettuce, volvox- colonial algae

Green Algae Spirogyra

Green Algae

Brown Algae Seaweed and kelp Has air bladder- gas-filled structures that keep algae floating near the surface for photosynthesis

Red Algae Feathery and fragile bodies Live in deep oceans

Fire Algae Dinoflagellates Bioluminescence- glow when disturbed in the water

Fire Algae Red tide- uncontrolled growth (algal bloom) of dinoflagellates. Release poisons that kill fish

Protozoans Classified by method of movement Rhizopods Ciliates Flagellates Sporozoans

Rhizopods Amoeba Move 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 Nucleus Plasma membrane Contractile vacuole Food particle engulfed by pseudopodia Food vacuole Pseudopodia cytoplasm

Ciliates Move by beating cilia Stentor Paramecium

Ciliates Cilia Contractile Vacuole micronucleus macronucleus Oral groove Anal pore

Flagellates Move by flagella Trypanasoma

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

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

Kingdom Fungi Review 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 Bread Mold-Rhizopus Sporangia Black Mold -Stachybotris

Rhizopus- Bread Mold spores sporangium sporangiophore Hyphae mycellium

Mushrooms

Mushroom development gills basidia cap spores button stipe

Yeast important in brewing and baking, make Penicillium

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