Across
  1. 2. reproductive structure of a fungus that grows from the mycelium
  2. 4. symbiotic association between a fungus and a photosynthetic organism
  3. 9. type of infection in which a virus enters a cell, makes copies of itself, and causes the cell to burst
  4. 13. protein coat surrounding a virus
  5. 14. symbiotic association of plant roots and fungi
  6. 16. structure used by protists for movement; produces movement in a wavelike motion
  7. 17. one of many long, slender filaments that makes up the body of a fungus
  8. 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
  9. 20. densely branched network of the hyphae of a fungus
  10. 21. structure produced by prokaryotes in unfavorable conditions; a thick internal wall that encloses the DNA and a portion of the cytoplasm
  11. 22. complex carbohydrate that makes up the cell walls of fungi; also found in the external skeletons of arthropods
Down
  1. 1. process in which paramecia and some prokaryotes exchange genetic information
  2. 3. a group of drugs used to block the growth and reproduction of bacterial pathogens
  3. 5. unicellular organism that lacks a nucleus
  4. 6. kind of virus that infects bacteria
  5. 7. RNA virus that contains RNA as its genetic information
  6. 8. bacteriophage DNA that is embedded in the bacterial host's DNA
  7. 10. disease-causing agent
  8. 11. type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
  9. 12. particle made of proteins, nucleic acids, and sometimes lipids that can replicate only by infecting living cells
  10. 15. preparation of weakened or killed pathogens used to produce immunity to a disease
  11. 18. short hairlike projection that produces movement
