| Protista (381) | The kingdom that includes all single-celled eukaryotic organisms. |
| protist (381) | the unicellular eukaryotic organism that belongs to the kingdom Protista |
| Endosymbiont Hypothesis (382) | Lynn Margulis proposed the theory stating that the first eukaryotic cell was formed from a symbiosis among several prokaryotes. We'll never be able to prove this. |
| Ciliophora (384) | the phylum containing solitary and colonial ciliates |
| ciliate (384) | A protist that has many hairlike structures that aid in movement; ciliates belong to the phylum Ciliophora. |
| cilium (384) | the short hairlike projection that produces movement in many cells |
| paramecium (384) | unicellular slipper-shaped ciliate protist |
| pellicle (384) | the complex living outer layer of certain protists |
| trichocyst (384) | the flask-shaped structure in the pellicles of some protists; it's used to defend and anchor the organism. |
| macronucleus (384) | the larger of 2 types of nuclei in ciliates, which controls the life process of the cell. |
| gullet (384) | the indentation on one side of a paramecium that brings food from the outside to the interior of the cell. |
| food vacuole (385) | a membrane-enclosed cavity in protists in which food is digested |
| anal pore (385) | the structure in paramecia and certain other protists through which waste materials are emptied into the environment |
| contractile vacuole (385) | the structure in some protists that collects water and discharges it from the cell |
| Zoomastigina (386) | the phylum that consists of animallike protists that move through the water by means of flagella |
| flagellum (386) | long, whiplike projection that aids in movement in some cells |
| flagellate (386) | an organism that has taillike structures that aid in movement |
| Sporozoa (387) | the phylum that contains nonmotile parasitic protists |
| Sarcodina (389) | the phylum that contains protists that use pseudopods to move and feed |
| pseudopod (389) | fingerlike projection of cytoplasm used for movement and feeding |
| ameba (389) | flexible active cell without cell walls, flagella, or cilia that moves by means of pseudopods, reproduces by binary fission, and belongs to the phylum Sarcodina |
| Euglenophyta (394) | the phylum that contains plantlike protists that move by means of flagella and have chloroplasts |
| euglena (395) | cell belonging to the phylum Euglenophyta that contains chlorophyll and has a pouch that contains 2 flagella and have chloroplasts. |
| Pyrrophyta (396) | the phylum that contains protists known as dinoflagellates |
| dinoflagellate (396) | the protist belonging to the phylum Pyrrophyta that typically is photosynthetic, moves by means of 2 flagella, and reproduces by binary fission |
| Chrysophyta (398) | the phylum tht contains yellow-green algae, golden-brown algae, and diatoms |
| diatom (398) | photosynthetic cell belonging to the phylum Chrysophyta that produces intricate cell walls rich in silicon |
| slime mold (398) | protist that is amebalike at one stage of its life and at other stages produces moldlike masses that give rise to spores |
| Acrasiomycota (398) | the phylum that contains cellular slim molds |
| Myxomycota (398) | the phylum containing acellular slime molds |
| plasmodium (399) | a mass of cytoplasm that contains many nuclei, such as the structure produced by acellular slime molds that contains thousands of nuclei enclosed in a single cell membrane |
| bloom (400) | enormous growth of algae, protists, and other organisms that results if too much waste is present in a body of water |
| phytoplankton (401) | any small photosynthetic organism found in great numbers near the surface of the ocean. |
