Document Summary
18. 1) protists are an extremely diverse assortment of eukaryotes. Protists are a diverse collection of mostly unicellular eukaryotes. Used to be classified in a kingdom called protista, but now it is thought that they constitute multiple kingdoms within domain. Protest is useful as a convenient term to refer to eukaryotes that are not plants, animals, or fungi. They obtain their nutrition in a variety of ways: some are autotrophs, who make their food by photosynthesis. Some are protozoans, they are heterotrophs, eat bacteria and other protists. Some are parasites, who derive their nutrition from a living host, which is harmed by this interaction. Some are mixotrophs, they can do both photosynthesis and heterotrophy depending on availability of light and nutrients. Most protists are aquatic, and are found almost anywhere there is moisture, including terrestrial habitats like damn soil, and leaf litter. Ex) protists that are endosymbionts in the intestinal tract of termites.
