are characterized by two flagella of different lengths. One propels the cell in a whirling motion. Also have cellulose plates.
Major component of plankton(which is eaten by jellyfish, corals, sea anemones, or giant claims) which provide carbohydrates to their host animals. Some are bioluminesecent, producing flash lights in tropical waters. Some a re parasites |

|
Definition
| results from a sudden population explosion, or "bloom" of dinoflagellates that turn the water red, orange, or brown. Ususally occurs when nutrients content of the water increses. Toxins from dinoflagellates may become concentrated in the tissuses of clams, scallops, oyster, and mussels. Which can cause a person to get posioning. |

|
|
Term
|
Definition
| related to euglena. are unicellular flagellates with elongated cells that primarly inhabit fresh waters. Most have long whiplike flagellum uses in locomtion and short flagellum ghat does not extend from cell. |

Definition
| photosynthtic quantic protsit with two flagella and carotenoid accessory pigments |
|
|
Term
|
Definition
| are primarly unicellular algae with two-part silica walls that confer varietY ornate shapes(pennate(glide in grove, are at the bottom sausage like.) centric(base in food chian and circular)Have glass shells which accumulate on the oceans floor, and make sediment on rocks. Also useful in pools fliters, polish, and toothpaste(make things shiny). |
|
|
Term
|
Definition
| similar to green algae in that they store carbohydrates as a modified form of starch, have cell walls containing cellulose, and produce chlorophlly a. Because it can be red or brown it also has phycocyanin and phycoerythin like cyanobacteria. have no flagella or cillia GLIDE. the cell wall contains agar which used to make jelly substances in canned meat or ice cream, also gels in electropharsis |
|
|
Term
|
Definition
| Most complex and largest protists. Olive green to brown. Reproduce by means of spores, each with two flagella. Seaweed and Kelp are underwater forests. MULTICELLULAR. Algin comes from it's cell walls help thicken substances such as ice cream, candies, dressings. ARE DIATOMS |
|
|
Term
|
Definition
| most plant like of the protist. Use chlorophyll a and b, use starach as a storage carbohydrate, and cell walls contain cellulose. Have alternative generations, with alternating multicellular haploid(gametophyte) and diploid(sporophyte) phases in their life cycle. Live in fresh water and testrial habitats, only 10% live in marrine. many are unicellar, colonial(DEPEND ON EACHOTHER), and multicellular. filamentous(chain like series of cells)XANTHOPHYLL, a&b CAROTENE. 90% IN FRESHWATER, 10% IN MARININE |

Definition
| green algae, light intensity can destroy cell walls, so they use caryotenes, |

|
Term
|
Definition
| no photosynthesis, some produce a filmentous feeding structure similar to those of fungi. Live with fungi, cell walls are chitin, characteristic of walls in fungi. live in damp habitats. Single, amoeboid cells and as large masses that behave as one multicellular organism. PARASITES OF ANIMALS AND PLANTS. POTATO FAMINE. exoenzymes-able to get food AND SAPATROPHIC-LEAVE OFF DEAD THINGS |

Term
|
Definition
| consist of plasmodium, a mass of thousands of diploid nuclei enclosed by a single cell memebrane. yellow blobs engluf bacteria and other microoganisms. ASEXUAL. in times of drought form stocks of sprongia that produce resistant haploid spores until favorable condition return, and germinate spores and form haploid cells. |

| live in termites stomach, they also include euglenoids and dinoflagellates, Can cause diseases by living in woman and cause discharge and can cause dirreah |
|
|
Term
|
Definition
| are common protozoe with complex cells, mostly unicellular, are characterized by abundant hairlike cilia. Propel through water. Cilia also sweep food(bacteria, algae, and other ciliates) into the cell's gullet. A food vacuole then surrounds and transports the captured meal inside cell. In some species, a permanent anal pores releases the wastes. Contractile vacuoles pump excess water out of the cell. Most free living like parmecium. |
