Study guide for a biology class covering a chapter on the two main groups of prokaryotes: bacteria and archaea. Includes a list of vocabulary terms and short answer questions.
Name: __________________________________ Period: ____________________ Date: _____________ Biology Study Guide Prokaryotes: Bacteria and Archaea Vocabulary Understand and be able to apply each of these terms. 1. Prokaryotes – 2. Bacterial shapes: a. Coccus – b. Bacillus – c. Spirilla – 3. Pili / Fimbrae – 4. Flagella – 5. Thylakoid membranes - 6. Respiratory membranes – 7. Nucleoid region – 8. Plasmids – 9. Binary fission – 10. Endospores – 11. Photoautotrophs – 12. Chemoautotrophs – 13. Photoheterotrophs – 14. Chemoheterotrophs – 15. Aerobic – 16. Anaerobic – 17. Nitrogen fixation – 18. Archaea – 19. Thermophile – Environmental Science Worksheets and Resources http://www.aurumscience.com Page 1 20. Halophile – 21. Methanogen – 22. Symbiotic relationships: a. Mutualism – b. Commensalism – c. Parasitism – 23. Pathogenic - 24. Exotoxins – 25. Endotoxins - Critical Thinking Be able to read, analyze, and give complete answers to questions like these. 1. How does the presence of a cell wall aid in the survival of bacteria? 2. Bacteria reproduce asexually, yet are still able to evolve. Explain how mutations, pili, and plasmids help them in doing so. 3. Bacteria, such as the one that causes tetanus, can infect living hosts even after laying dormant in the soil for years. How are they able to do this? 4. Two new prokaryotic species are discovered. One is found in an underwater volcanic vent, the other is found in the small intestine of humans. Which is probably a bacteria, and which is probably an archaea? 5. How are bacterial diseases usually treated? 6. Why are prokaryotes so important to the biosphere? 7. Deep-sea angler fish have a bioluminescent “lure” attached to their head. This lure helps them attract prey. The light is produced by bacteria. Explain what kind of symbiotic relationship this would be.
