Bio1151b Chapter 28 Protists
  1. The kingdom formerly known as           is crumbling. Protists are more diverse than any other eukaryotes and consist of              as well as           organisms.
  2. In the food web, protists can be                  , which contain chloroplasts,               , which absorb or ingest food, or a combination called             .
  3. Much of protist diversity has its origins in serial endosymbiosis.
  4. Euglenozoa, such as Euglena, contain a crystalline rod inside their           .
  5. Dinoflagellates are photosynthetic and often contain internal plates of            ; two           propel them through water in a spinning motion.
  6. Ciliates use        to move and feed. An example is Paramecium, which can undergo genetic recombination by conjugation.
  7. Golden algae (              ) can be unicellular or colonial and contain yellow and brown              for photosynthesis.
  8. Brown algae (             ), are multicellular "seaweeds" that include Giant       which forms aquatic "forests", and            Weed which has air bladders to help it float.
    • An innovation among the multicellular algae is the              of generations.
  9. Red algae and green algae are the closest relatives of land plants.
    • Red algae (             ) contain the pigment                , which masks the green of              . Some are multicellular, edible "seaweeds".
    • Green algae (              ) contain               that give them their green color. The               can live symbiotically with fungi as          .
