Across
- 3. any of various pathogenic bacteria, especially one that is rod shaped
- 5. a bacterium with a rounded or spherical shape
- 7. a fairly rigid helically twisted bacteria cell, often, but not necessarily, a member of the genus spirillum
- 8. Fission a method of asexual reproduction in which a organism splits into two
- 10. a virus that uses RNA as its genetic material
- 12. Anaerobes a microorganism that can live and grow with or without molecular oxygen
- 13. a type of prokaryote, that is a unicellular organism without a cell nucleus
- 15. organism whose cell does not have a nucleus in which DNA is housed lack many organelles
- 17. an agent, (especially a virus, bacterium, or other microorganism), causing disease or illness to its host
- 19. a domant, tough, and non reproductive structure produced by a small number of bacteria
Down
- 1. Cycle the process in which a virus overtakes a cell and uses the cellular machinery of its host to reproduce
- 2. Anaerobes the opposite of obligate aerobes. they require the absolute absence of oxygen to survive
- 4. a large group of bacterium having simple cells with rigid cell walls and often flagella
- 6. Fixation the incorporation of atmospheric nitrogen into ammonia by various bacteria
- 9. sexual process in which two lower organisms of the same species (some algae and fungi) exchange nuclear material during a temporary union
- 11. virus that invades bacteria and consists of a core of nucleic acid, a capsid, and a tail
- 14. non cellular particle made up of genetic material and protein that can invade living cells
- 16. Cycle a form of viral reproduction involving the fusion of the nuclei acid of a bacteriophage with that of a host, followed by proliteration of the resulting prophage
- 18. the latent form of a bacteriophage in which viral genes are incorporated into bacterial chromosomes disrupting the bacterial cell
