  7. 20. duplicate of bacteria chromosome that may later develop into a bacterial cell.
  8. 21. chemical reactions using energy to grow, survive & reproduce
  9. 23. infectious agents, tightly folded strands of RNA, smaller than viruses. Cause many diseases in plants destroying millions of dollars’ worth of potato, citrus and other crop plants.
  10. 24. (identifying, naming and classifying)

  12. 26. needs oxygen
Down
  1. 1. virus doesn’t take over or kill the host cell right away, but does begin to replicate.
  2. 2. small self-replicating extra DNA with a few genes.
  3. 3. enclosing the cell wall, helps this bacteria attach to teeth and other interesting surfaces and protects it from infection fighting cells.
  4. 4. the most common prokaryotic cells. (true bacteria)
  5. 5. heat lovers
  6. 7. infectious, disease causing.
  7. 9. bacteria that help provide food and oxygen.
  8. 11. salt lovers
  9. 12. may cause disease
  10. 14. no membrane-bound nucleus.
  11. 16. does not need oxygen
