  3. 11. Protein coat surrounding a virus
  4. 12. One of the many long slender filaments that make up the body of a fungus
  5. 13. Disease causing agent
  6. 14. Reproductive structure of a fungus that grows from the mycelium
  7. 15. Kind of virus that infects bacteria
  8. 16. Structure used by protists for movement; produces movement by a wave-like motion
  9. 19. Type of infection in which a virus embeds its DNA into the DNA of the host cell and is replicated along with the host cell's DNA
  10. 20. Structure produced by prokaryotes in unfavorable conditions thick internal wall that encloses the DNA and a portion of the cytoplasm
  11. 21. Life cycle that has two alternating phases a haploid phase and a diploid phase
  12. 22. Group of drugs used to block the growth and reproduction of bacterial pathogens
Down
  1. 1. Unicellular organism that lacks a nucleus
  2. 2. Symbiotic association between a fungus and a photosynthetic organism
  3. 3. Process in which paramecia and some prokaryotes exchange genetic information
  4. 4. RNA virus that contains RNA as its genetic information
  5. 5. Type of infection in which the virus enters a cell, makes a copy of itself, and causes the cell to burst.
  6. 7. Complex carbohydrate that makes up the cell walls of fungi; also found in the external skeletons of arthropods
  7. 8. Bacteriophage DNA that is embedded in the bacterial host's DNA
  8. 10. Preparation of weakened or killed pathogens used to produce immunity to a disease
  9. 15. Process in which a cell replicates its DNA and then divides in half to produce two identical cells
  10. 17. Particle made of protein, nucleic acids, and sometimes lipids that can replace only by infecting living cells
