2. ANIMAL-LIKE PROTISTS PLANTLIKE PROTISTS FUNGILIKE PROTISTS GROUPCiliates, amoebas, apicomplexans, and zooflagellates Euglenoids, diatoms, dinoflagellates, algae Slime molds, water molds, and downy mildews EXAMPLE AmoebaGreen AlgaeSlime Mold DISTINGUISHING CHARACTERISITICS Considered animal-like because they consume other organisms for food Some are parasites Considered plant-like because they make their own food through photosynthesis Some consume other organisms or are parasites when light is unavailable Considered funguslike because they feed on decaying organic matter and absorb nutrients through their cell walls Some slime olmds consume other organisms and a few are parasitic

3. Protists can be found typically in damp or aquatic environments. Such as decaying leaves, damp soil, ponds, streams, and oceans. Microsporidia are microscopic protozoans that cause disease in insects and some species are used as insecticides. Green algae lives in the hair of sloths and helps them blend in with their environment. (symbiotic relationship)

4. CiliophoraSarcodinaApicomplexaZoomastigina Group Paramecium, Stentor, Trichodina pediculus Amoeba, RadiolariansPlasmodium (malaria causing) Three species causes infectious disease in humans that are often fatal Example ParameciumAmoebaMalaria Infected Cells Tsetes Fly Distinguishing Chracterisitics All have numerous short, hairlike projections called cilia for movement Most aquatic environements, oceans, lakes, rivers and mud Reproduce asexually be by binary fission All use pseudopods for feeding and locomotion. Most found in saltwater Reproduce asexually Also known as sporozoans because they produce spores at some point in their life. Spores are reproductive cells that form without fertilization. All sporozoans are parasitic Also known as zooflagellates because all use a flagella for movement.

5. DiatomsDinoflagellatesEuglenoidsAlgae Group Chlorophyll & secondary pigment called Carotenoids (golden yellow) Some have red photosynthetic pigments Share characteristics of both plants and animals Brown, Green, Red Example Distinguishing Characteristics Unicellular algae Photosynthetic autotrophs Convert food to oil Reproduce sexually and asexually Most unicellular & have 2 flagella Some are bioluminescent Most found in saltwater Some autotrophic, some heterotrophic Unicellular Most found in freshwater Cell wall is replaced by a pellicle, which allows them to crawl through mud Brown algae is massive, kelp Green algae is diverse with over 7000 species Red algae have phycobilin that allow them to absorb green, violet, & blue light that can penetrate water to a depth of 100m!

6. Acellular Slime MoldCellular Slime MoldWater Molds & Downy Mildew Group Go through a stage in their life cycle in which the nucleus divides but no internal wall forms, resulting in a mass of cytoplasm with multiple nuclei Spend most of their life as single amoeba-like cells with no flagella Close to a fungus, but water molds produce flagellated reproductive cells and cells walls are composed of cellulose Example Distinguishing Chracteristics Feed on decaying matter Reproduce using spores Cell walls contain cellulose Creep over rich, moist soil & engulf bacteria Reproduce sexually and asexually Live in water or damp places Some absorb nutrients from water or soil & some from other organisims
