| protist | eukaryotic organism that is not an animal, a plant, or a fungus |
| protozoan | animal-like protist; is a heterotroph |
| alga | plant-like protist; makes its own food by photosynthesis |
| zooflagellate | member of a group of protozoans that move by means of one ore more flagella |
| pseudopodium | temporary extension of a cell's cytoplasm and plasma membrane; used by certain protozoans in movement and feeding |
| foram | member of a group of marine protozoans with porous shells made of organic material and calcium carbonate |
| ciliate | member of a group of protozoans that move and feed by means of hairlike projections |
| plasmodial slime mold | member of a group of fungus-like protists that grows in a branching pattern |
| plasmodium | mass of cytoplasm, undivided by membranes or cell walls and containing many nuclei; characteristic of certain protists |
| sporangia | reproductive structure on a plasmodial slime mold; also called a fruiting body; spore-forming structure at the tip of a fungal hypha |
| cellular slime mold | protist with both unicellular and multicellular stages in its life cycle; is a decomposer |
| euglenoid | member of a group of unicellular photosynthetic protists with one or two flagella and no cell wall |
| dinoflagellate | member of a group of unicellular, photosynthetic algae with cell walls made of cellulose and two flagella |
| plankton | mostly microscopic organisms that drift or swim near the surface of ponds, lakes, and oceans |
| phytoplankton | microscopic algae and cyanobacteria that carry out photosynthesis |
| zooplankton | micorscopic animals that swim or drift near the surface of aquatic environments |
| diatom | member of a group of unicellular algae with glasslike cell walls |
| seaweed | a large, mulitcellular marine alga |
| endosymbiosis | process by which eukaryotic cells may have evolved from small symbiotic prokaryotes that lived within other, larger host cells |
