|---|
| protozoan | one-celled animal-like protist |
| eukaryote | cells have a nucleus and contain membrane-bound organelles |
| autotrophs | organisms that make their own food by photosynthesis |
| heterotrophs | organisms that eat other organisms |
| fungus-like protist | protist that feeds on decaying organic matter and absorb nutrients through cell walls |
| plant-like protist | protist that makes their own food through photosynthesis |
| animal-like protist | protist that eat other organims, some are parasites |
| microsporidia | microscopic protozoans that live in the guts of termites |
| endosymbiosis | theory that suggests eukaryotes formed when a large prokaryote engulfed a smaller one |
| centrioles | small, cylindrical organelles used in cell division (mitosis) |
| nutrition | scientists classify protists by the way they obtain this: |
| cilia | short, hairlike projections |
| pellicle | tough outer membrane of some protists |
| trichocysts | long, cylinder-shaped bodies that discharge spinelike structures |
| contractile vacuole | structure that collects extra water and expels it from the cell |
| macronuclei | nuclei that control the everyday life functions such as feeding |
| micronuclei | nuclei that are used for reproduction |
| binary fission | asexually reproduction where the cell pinches in and divides into 2 cells |
| conjugation | sexual reproduction process where genetic information is exchanged |
| pseudopod | temporary extension of the cytoplasm |
| fungus-like protist | protists that feed on decaying organic matter |
| diffusion | process amoebas use to excrete wastes |
| spores | reproductive cells that form without fertilization and produce a new organism |
| sporozoans | are parasites |
| Plasmodium | causes Malaria |
| Zooflagellates | use flagella for movement |
| Amoeba | use pseudopod for feeding and movment |
| Paramecium | use cilia for feeding and movment |
| flagella | long, whiplike projections from the cell |
| chlorophyll | pigment found in algae that is used in photosynthesis |
| phytoplankton | base of the food web and provide much of the Earth's oxygen |
| carotenoids | pigment that makes diatoms appear golden yello |
| diatoms | give toothpaste its gritty texture |
| bioluminescent dinoflagellates | emit light |
| blooms | population explosions of dinoflagellates |
| euglena | protist that is autotroph but can be heterotroph in absence of light |
| colony | group of cells that join together in close association |
| kelp | example of brown algae |
| red algae | type of algae that can live deep in the water and forms the coral reefs |
| alternation of generations | life cycle of algae |
| chloroplast | organelle used in photosynthesis |
| red tides | caused by dinoflagellates with red pigments |
| fragmentation | green algae break into pieces and each piece grows into a new organism |
| acrasin | chemical that starving cells give off to signal the amoebas to gather and form a colony |
| water molds | members of phylum Oomycota |
