Document Summary
Protists: eukaryotes that are not animals, land plants, or true fungi. Algae: usually photosynthetic: microalgae: unicellular or small colonies, macroalgae: large, complex, cytoskeleton. Components of eukaryotic cells (from a protest perspective) Shape determined skeleton usually varied in protists adds more variation/complexity than in animal cells. Some protist"s shapes are more determined by extracellular structures. Is not a modified version of prokaryotic flagellum. Motors that power the flagellum occur all the way along it not: expend energy to pump water out of cell using vesicles just in the cell membrane. Vesicles containing water fuse together to create a large vacuole vacuole fuses with membrane to expel water. Endocytosis: especially phagocytosis, most protozoa are phagotrophs. Early eukaryotes did well by acting as predators : some groups of algae also use phagocytosis. Nucleus houses the genome: surrounded by an envelope, genome varies in size. In general, eukaryotes have bigger genomes than prokaryotes. Nucleus division and asexual reproduction: binary fission.
