protists
| Question | Answer |
|---|---|
| unicellular or multicellular eukaryotes that lack differentiation | protists |
| Protist disease spread by untreated water, common in streams | Giardiasis |
| the process in which two paramecia come together after meiosis to exchange genetic material | conjugation |
| temporary extensions of cytoplasm used for locomotion | pseudopodia |
| three modes of locomotion in protists | cilia, flagella, pseudopodia |
| sleeping sickness is caused by | Trypanosoma |
| sleeping sickness is transmitted by | Tse tse fly |
| most common habitat for algae | aquatic |
| unicellular or multicellular, photosynthetic, various body forms, unicellular gametangia | algae |
| common traits of Chlorophyta and Plants | chlorophylls a&b, store food as starch, cell walls |
| protist that is both heterotrophic and autotrophic | Euglena |
| used to produce detergents, paint removers and toothpaste | diatomaceous earth |
| common diseases caused by protists | amebiasis, malaria, leishmaniasis |
| how does a Paramecium move | cilia |
| how does an Amoeba move | psuedopodia |
| how does a Euglena move | flagella |
| all members of this phylum are parasites | Apicomplexa |
| transmits malaria | Anopholes mosquito |
| protist that causes malaria | Plasmodium |
| vaginal infection | Trichomonas |

| colonial green algae from lab | Volvox |
| common example of ciliate from lab | Paramecium |
| filamentous green algae from lab | Spirogyra |
| Protozoa that moves with pseudopodia from lab | Amoeba |
| Unicellular with one flagellum, can be heterotrohic or autotrophic | Euglena |
| structure in Paramecium used to prevent cytolysis | contractile vacuole |
| phylum that has no disease causing species | Ciliates |
