2. A substance introduced into a body to stimulate the production of chemicals that destroy specific disease-causing viruses and organisms
5. A small, rounded, thick- walled resting cell that forms inside a bacterial cell
8. A long, whip like structure that helps a cell to move
9. The region of a cell located inside the cell membrane or between the cell membrane and nucleus; contains a gel like material and cell structure
11. An illness that can pass from one organism to another
13. A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parent
15. A poison that can harm an organism
16. Single celled organisms that lacks a nucleus; prokaryotes
17. The process of breaking down food to release its energy
18. A virus that infects bacteria

21. A tiny, nonliving particle that invades and then reproduces inside a living cell

1. A form of asexual reproduction in which one cell divides to form two identical cells
3. The process in which a unicellular organism transfers some of its genetic material to another unicellular organism
4. An organism that breaks down chemicals from dead organisms and returns important materials to the soil and water
6. An organism that lives on or in a host and causes harm to the host
7. A process of heating food to a temperature that is high enough to kill most harmful bacteria without changing the taste of the food
10. A reproductive process that involves only one parent and produces offspring that are identical to the parent
12. Tiny structure located in the cytoplasm of a cell where proteins are produced
14. An organism that provides a source of energy or a suitable environment for a virus or another organism to live
19. A chemical that can kill bacteria without harming a person's cell
