Protists Description
Protist Characteristics
| Question | Answer |
|---|---|
| eukaryotic one-or many-celled organism that lives in moist/wet environments; some are plant-like and contain chlorophyll;some are animal-like and can move | Protist |
| Protist are difficult to classify; they are grouped based on characteristics shared with | plants, animals,and fungi |
| the evolution of protist is studied through | fossils and genetic material |
| Plant-like protist that contain chlorophyll to make food | Algae |
| Found in fresh and salt water, make glasslike boxes which can form fossils | Diatoms |
| Also known as fire algae because they produce a chemical that causes them to glow in the dark;use flagellum to move in their salt-water enviroments | Dinoflagellates |
| long, thin, whip-like structure used for movement | flagellum |
| Have characteristics of both plants and animals; when light is present they make their own food; an eyespot helps them move toward light;when there is no light, they eat bacteria and other protist. | Eugenoids |
| also called sea weed;are usually many-celled; can live at the depth of 175 m; contain chlorophyll and large amounts of red pigment. | red algae |
| contain large amounts of chlorophyll and can be one-celled or many-celled; some scientist say they evolved from green algae. | brown algae |
| a many-celled form of brown algae; is an important source of food and shelter for aquatic(sea-life) organisms | kelp |
| Algae,a source of food for ocean organisms are called | grasses of the ocean |
| Algae produce oxygen through | photosynthesis |
| Results of imbalances that can cause enviromental problems is called an | algae bloom |
| Algae can be used for | food and cosmetics |
| One-celled animal protist | protozoans |
| Thread-like structures that extend from their cell membranes | cilia |
| have two nuclei;the micronucleus is involved in reproduction while the macronucleus controls other cell functions | paramecium |
| Ciliates eat | bacteria |
| Means "false foot"; are used by some protist to move about and trap food. | pseudopods |
| One-celled protist reproduce | asexually |
| 3 types of protist groups | plant-like , animal-like, funguslike |
| Animal-like protist | protozoans |
| plant-like protist | algae |
| funguslike protist | slime mold, water molds, and downy mildews |
| These are parasites that cause disease | Amoebas |
