of next week's lab to earn credit. 1. Kingdom Archaebacteria and Kingdom Bacteria differ because A. prokaryotic. members of Kingdom Archaebacteria are eukaryotic and members of Kingdom Bacteria are B members of Kingdom Archaebacteria are only found in extreme (salty, low pH, very hot, C. very cold) habitats and members of Kingdom Bacteria are never found in extreme habitats. members of Kingdom Archaebacteria are photosynthetic and members of Kingdom Bacteria are heterotrophic. D. members of Kingdom Archaebacteria and members of Kingdom Bacteria are prokaryotic but differ in their cell wall materials, RNA polymerases, and DNA sequences. 2. The process of body cell division among prokaryotes is called A. binary fusion. binary fission. C. mitosis. Prokaryotic cells don't divide. None of these statements is correct. 3. Prokaryotic cells are able to exchange DNA through a process called A. sexual recombination. B. DNA-swapping. C. conjugation. - D. Prokaryotic organisms don't exchange DNA. None of these statements is correct. 4. Although prokaryotes are said to be "basically single-celled," the cells of some species can cooperate with other cells of the same species. What is NOT a way that these cells can cooperate with each other? A. Some cells develop specialized functions such as the ability to fix nitrogen. B. Clusters of cells may develop a mucilagenous/gelatinous sheath. C. Cells may link together in long filaments that exhibit waving motions. D. Their cytoplasm is directly connected among cells. Most bacterial cells are A. heterotrophic. B. photosynthetic. C. free-living nitrogen-fixers. D. larger than eukaryotic cells. Cyanobacterial cells can form filaments called A. heterocysts. B. trichomes. C. flagella. D. tails.

3. (3 pts) Show the structures of the protonated alcohols formed as intermediates in each of the above (c) 7. Draw the three shapes of bacterial cells: A. coccus B. bacillus C. spirillum 8. Cyanobacteria are A . autotrophic B . mixotrophic (heterotrophic OR autotrophic depending on environmental conditions) C. heterotrophic 9. A single ("discrete") bacterial colony on an agar plate consists of millions of cells. The colony is made up of A. bacterial cells of the same species that migrated to the same location in response to a signal. B. the progeny of two bacterial cells that underwent conjugation and many generations of cell division. C. the progeny of a single bacterial cell by many generations of binary fission. D. a mixture of cells that happened to be close to each other on the plate, all dividing and contributing to the colony. 10. Rhizombium is a bacterium that is able to fix nitrogen. It lives within nodules formed on the roots of plants of the family. For this reason, plants from this family are able to enrich soil naturally. A. Rose B. Bean (Legume) C. Sunflower D. Orchid
