Review Questions for lecture 20 Be familiar with the following terms: Eukaryote Nucleus Endomembrane system Cytoskeleton Exocytosis Phagocytosis Mitosis Haploid Diploid Alternation of generations Endosymbiont Genetic isolation Mitochondrion Plastid Chloroplast Monophyletic/Polyphyletic Primary vs Secondary Symbiosis Please review the effects of size on the life of the cell. How does having mitochondria effectively increase the respiratory surface area of a Eukaryotic cell? How does the ability to phagocytose effectively increase the ability of a Eukaryotic cell to take up nutrients? How do intestinal vili and microvili provide a better surface area/volume ratio for absorption of nutrients? Why can’t a large Eukaryotic cell depend upon diffusion for intracellular transport? How do the endomembrane system and cytoskeleton solve this problem? To what extent are the endomembrane system and cytoskeleton uniquely Eukaryotic features? What is the problem with replicating linear chromosomes? How do Eukaryotes solve this problem? Consider the typical Bacterial and ARchaeal method for segregating replicated chromosomes—it works fine for one chromosome. Now consider the adder’s tongue fern, which has over one thousand chromosomes: would the simple Bacterial system work? Why is mitosis necessary? Why is the relationship between Aphids and Buchnera an obligate relationship? Why is it a complementary relationship? Buchnera cannot be cultured in the laboratory—how do we know what it can do? On what basis can we classify it as a member of the proteobacteria? Why does Buchnera do OK without any two-component systems? Without a Krebs cycle? Without an electron transport chain? Why would it still have ATPase? Given Buchnera ’s environment, would you predict that it had a gene for CRP? Would you predict that it had attenuators for its amino acid synthesis operons? What is meant by monophyletism?
