  9. 9. Chemoautotroph <br />Organism that makes organic carbon molecules from carbon dioxide using energy from chemical reactions.<br />
  10. 10. Obligate Aerobe <br />Organism that requires a constant supply of oxygen in order to live.<br />
  11. 11. Obligate Anaerobe <br />Organism that cannot live in the presence of oxygen.<br />
  12. 12. Facultative Anaerobe <br />Organism that can survive with or without oxygen.<br />
  13. 13. Binary Fission<br />Type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells.<br />
  14. 14. Conjugation <br />Form of sexual reproduction in which paramecia and some prokaryotes exchange genetic information.<br />
  15. 15. Endospore <br />Type of spore formed when a bacterium produces a thick internal wall that encloses its DNA and a portion of its cytoplasm.<br />
