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