Organisms

5. – Prokaryotes that often live in very harsh or extreme environments.
6. – Short, hair-like structures that help some protists swim.
8. – A whip-like structure used by some prokaryotes for movement.
10. protective outer protein shell of a virus.
12. – A preparation that helps the immune system recognize and fight a specific virus.
14. – A type of virus that has RNA instead of DNA as its genetic material.
18. – Long, thin filaments that make up the body of a multicellular fungus.
19. – A living cell that a virus must enter in order to reproduce.
20. – A diverse group of eukaryotic organisms that are not plants, animals, or fungi.

1. – A thick mass of tangled hyphae found underground.
2. – A role for bacteria that involves breaking down dead matter to recycle nutrients.
3. – The tough material that makes up the cell walls of fungi.
4. – An organism that lives on or inside another organism and causes it harm.
7. – An infection cycle where a virus enters a cell, makes copies, and causes the cell to burst.
9. FISSION – The process by which a bacterium divides to produce two identical cells.
11. – The process of heating food to a high temperature to kill harmful bacteria.
13. – Plant-like protists that produce their own food through photosynthesis.
15. – A symbiotic relationship between a fungus and a photosynthetic partner like algae.
16. – A tiny reproductive cell that can grow into a new fungus.
17. – A "false foot" used by amoebas for movement and catching food.
