Across
  1. 4. cycle / bacteriophage life cycle in which the virus incorporates its DNA into that of a bacterium; occurs preliminary to the lytic cycle
  2. 6. / long, slender extension used for locomotion by some bacteria, protozoans, and sperm
  3. 8. / organism able to synthesize organic molecules by using carbon dioxide as the carbon source and the oxidation of an inorganic substance such as hydrogen sulfide as the energy source
  4. 10. / photosynthetic bacterium that contains chlorophyll and releases oxygen; formerly called a blue-green alga
  5. 13. / spore formed within a cell
  6. 14. / transfer of genetic material from one cell to another
  7. 15. / type of archaea that lives in extremely salty habitats
  8. 16. / a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease
  9. 17. / type of archaea that lives in oxygen-free habitats such as swaps, and releases methane gas
  10. 20. / protective protein containing the genetic material of a virus
Down
  1. 1. cycle / bacteriophage life cycle in which the virus takes over the operation of the bacterium immediately upon entering it and subsequently destroys the bacterium
  2. 2. / organism that is unable to produce its own organic molecules, and therefore requires organic nutrients in its diet
  3. 3. / small, bristle like fiber on the surface of bacterial cell, which attaches bacteria to a surface; also fingerlike extension from the oviduct near the ovary
  4. 5. / virus that infects bacteria
  5. 7. / symbiotic relationship between certain fungi and algae, in which the fungi possibly provides inorganic food or water and the algae provides organic food
  6. 9. anaerobe / prokaryote that is able to grow in either the presence or the absence of gaseous oxygen
  7. 11. virus / newly identified viruses that are becoming more prominent
  8. 12. / prokaryotes with biochemical characteristics that distinguish them from both bacteria and eukaryotes
  9. 16. fission / splitting of a parent cell into two daughter cells; serves as an asexual form of reproduction in bacteria
  10. 18. specific / organisms that can be infected by a virus, specifically
  11. 19. / region of prokaryotic cells where DNA is located; it is not bounded by the nuclear envelope
