Chapter 28 Kingdom Protista. This Kingdom has been used as a catch-all for any unicellular organism that doesn’t fit into one of the other 4 Kingdoms. There are also some species that live in colonies which function a lot like a higher level organism. Some of these organisms seem like plants, and others seen like animals, thus there is a great deal of diversity in this Kingdom. 1) What is a Mixotroph? Give an example. 2) What do the terms “protozoa” and “algae” mean, and what are their roles in taxonomy? 3) How do cilia and flagella of Eukaryotes (both found in protists) differ from Prokaryotic flagella? *Draw the 9 + 2 arrangement in figure 7.25 and the protein structure in figure 27.5 4) What is a formation that many protists can hide in to survive harsh environments? They are analogous to prokaryotic endospores. 5) How large a role do plankton play in the food web? 6) What is the “serial endosymbiosis” hypothesis? Also explain the order in which the process occurred and the evidence for this phylogeny. 7) List 6 pieces of evidence which support the endosymbiotic origin of modern Eukaryotes. 8) Why is the 3 Domain system with 5 Candidate Kingdoms considered better than the current 5 Kingdom of proposed 8 Kingdom system? (hint: look into phylogenetic patterns from chapter 25 question 13.) 9) What characteristic distinguishes Archaezoans? (Hint organelle) Example species? 10) What characteristic distinguishes Euglenazoans?
