| Protist | any organism that is not a plant |
| pseudopod | temporary cytoplasmic projections |
| amoeboid movement | type of locomotion used by amoebas |
| food vacuole | small cavity in the cytoplasm of protists that temporarily stores food |
| cilium | short hairlike pojection similar to flag |
| trichocyst | small, bottled shaped structure used for defence bt paramecia |
| macronucleus | the larger of a cilate's two nuclei, contains multiple copies of most of the gene that the cell needs in its day-to-day existance |
| micronucleus | the smaller of ciliate's two nuclei |
| gullet | indentation in one side of a ciliate that allows food to enter the cell |
| anal pore | region of the cell membrane of a ciliate where waste-contained food vaculoles fuse and are then emptied into the enviroment |
| contractile vacuole | cavity in the cytoplasm of some protists that collects water and discharges it from the cell |
| conjugation | form of sexual reproduction in which paramecia and some prokaryotes exchange genetic information |
| accessory pigment | compound other than chlorophylle that absorb lightat different wavelengnths |
| eyespot | group of cells that can detect changes in the amount of light in the enviroment |
| pellicle | cell membrane in eugglenas |
| phytoplankton | population of algae and other small photosythetic organism found near the surface of ocean and forming part of plankton |
| phycobilin | accessory pigment found in red algae that is especially good at absorbing blue light |
| filament | in algae, a long threadlike colony formed by many green algae |
| alternation of generations | process in which many algae switches back and forth between haploid and diploid stages of their life cycle |
| gametophyte | haploid, or gamete-producing, phase of an organism |
| spore | haploid reproducing cell |
| sporophyte | diploid, or spore-producing, phase of an organsism |
| cellular slime mold | slime mold whose individual cells remain separated during every phase of the mold's life cycle |
| acellular slime mold | slime mold that passes through a stage in which its cells fuse to form large cells with many nuclei |
| fruiting body | slender reproductive structure that produces spores and is found in some funguslike protists |
| plasmodium | structure with many nuclei formed by acellular slime molds |
| hypha | tiny filiment that makes up a multicellular fungus or a water mold |
| zoosporangium | spore case |
| oogonium | specialized structure formed by hyphase that produces female nuclei |
