Across
  1. 5. Spiral-shaped bacteria.
  2. 7. Tiny hair-like structures used by some protists for movement.
  3. 9. A substance used to stimulate the immune system to create defenses against a specific pathogen, providing immunity before sickness occurs.
  4. 10. A eukaryotic organism (its cells have a nucleus) that is not an animal, plant, or fungus; a "catch-all" category.
  5. 11. An organism (like a mosquito) that transmits a pathogen from one host to another.
  6. 14. A whip-like tail structure used by some protists for movement.
  7. 16. "False feet," or temporary projections of a cell, used for movement and feeding.
  8. 19. A medicine that specifically targets and kills bacteria or stops them from reproducing.
  9. 20. Microscopic "seeds" that fungi use to reproduce and spread.
Down
  1. 1. Sphere-shaped bacteria.
  2. 2. Rod-shaped bacteria.
  3. 3. Fission The process bacteria use to reproduce by splitting in two.
  4. 4. Cell A living cell that a virus invades to use its machinery for reproduction.
  5. 6. A bacterium, virus, or other microorganism that can cause disease.
  6. 8. Single-celled, living microorganisms that are prokaryotic (they do not have a nucleus).
  7. 12. A type of single-celled fungus.
  8. 13. A type of multicellular fungus that grows in thread-like structures.
  9. 15. Eukaryotic organisms (cells have a nucleus) that get food by absorbing nutrients from their surroundings (decomposers); they are not plants.
  10. 17. A common type of "animal-like" protist that can move on its own.
  11. 18. A tiny, non-living particle that must invade a living host cell to replicate.
