Cards Term protist Definition an organism that is not a plant, animal, fungi, prokaryote, or a bacterium Term Protista Definition comes from the Greek word meaning "the very first" Term Zoomastigina (zooflagellates) Definition animal-like protists that swim using flagella Term examples of zooflagellates Definition Trichomas vaginalis, Leishmania donovani, etc. Term Sarcodina Definition plylum for sarcodines Term sarcodines Definition animallike protists that use pseudopods for feeding and movement Term amoeboid movement Definition type of motion used by sarcodines Term food vacuole Definition small cavity in the cytoplasm that temporarily stores food Term Ciliophora Definition phylum for ciliates Term ciliates Definition use cilia for movement Term cilia Definition shortlike hair projections (similar 2 flagella) that are used for movement Term Trichocysts Definition very small, bottle-shaped structures used for defense Term macronculeus Definition the larger of a ciliate's 2 nuclei that contains multiple copies of most of the genes that the cell needs in its day-to-day activities Term micronucleus Definition the smaller of a ciliates 2 nuclei that contains a "reverse copy" of all the cell's genes Term gullet Definition an indentation in one side of cilia that is used to sweep food particles into Term anal pore Definition region of the cell membrane of a ciliate where waste-containing food vacuoles fuse and are then emptied into the environment Term contractile vacuoles Definition cavities in the cytoplasm that are specialized to collect water Term conjugation Definition process where cells exchange genetic information (occurs with ciliates) Term Sporozoa Definition phylum for sporozoans Term sporozoa Definition do not move on their own and are parasitic Term Examples of disease causing protists and their diseases Definition Mosquitos (malaria), tsetse flies (African sleeping sickness), etc Term algae classification Definition photosynthetic pigments Term Accesory pigments Definition compounds other than chlorophyll that obsorb light at different wavelengths than chlorophyll Term Euglenophyta Definition phylum for euglenophytes Term euglenophytes Definition primarily photosynthetic, live in freshwater, and have 2 unequal flagella Term pellicle Definition flexible outer covering of a euglena that allows it to change direction swiftly Term Chrysophyta Definition phylum for chyrsophytes Term Chrysophyta Definition includes yellow-green algae and golden-brown algae Term chysophytes Definition plantlike protists that have goldn-colored chloroplasts Term Bacillariophyta Definition phylum for diatoms Term diatoms purpose Definition produce thin, delicate cell walls of silicon (the main component of glass) Term Pyrrophyta Definition phylum for dinoflagelletes Term Pyrrophyta Definition live in saltwater, are phtosynthetic, and have rigid cell walls of cellulose Term Phytoplankton Definition population of algae and other small, photosynthetic organisms found near the surface of the ocean and forming part of plankton Term Rhodophyta Definition phylum for red algae Term red algae Definition live almost entirely in saltwater, contain the red pigment phycobilins Term phycobilins Definition accessory pigment found in red algae that is especially good in absorbing blue light Term Phaeophyta Definition phylum for brown algae Term brown algae Definition live in almost entirely in saltwater, multicellular, and contain the brown pigment fucoxanthin Term Chlorophyta Definition phylum for green algae Term green algae Definition live in fresh and saltwater, have food stored as starch, have chlorophyll simialr to that in vascular plants Term examples of brown algae Definition giant kelp, fuccus Term filaments Definition long threadlike colonies Term filaments Definition long threadlike colonies Term alternation of generations Definition process in which many algae switch back in forth beween haploid and diploid stages of thei life cycles Term gametophytes Definition gamete-producing plants Term sporophytes Definition spore-producing organisms Term slime molds Definition funguslike protists that play key roles in recycling organic material Term Acrasiomycota Definition phylum for cellular slime molds Term cellular slime molds Definition cells spertaed by cell membranes Term fruiting body Definition a slender, reproductive structure that produces spores Term Myxomycota Definition phylum for acellular slime molds Term acellular slime molds Definition pass through a stage in which their cells fuse to form large cells with many nuclei Term Oomycota Definition phylum for water molds Term oomycetes (water molds) Definition thrive on dead or decaying organic matter in water and some are plant parasites on land Term oogonium Definition produce female nuclei in water molds Term antheridium Definition produce male nuclei in water molds
