(Living) Chap 18
VIRUS
(Non-Living)
1. Bacteria (p. 516)
a single celled organism lacking a nucleus.
2. Nucleoid (p. 518)
organism that must take in organic molecules for both energy and carbon.
3. Capsule (p. 518)
organism that is photosynthetic but needs organic compounds as a carbon source.
4. Pilus (p. 518)
organism that makes organic carbon molecules from carbon dioxide using energy
from chemical reactions.
5. Binary fission
(p. 520)
organism that uses energy from sunlight to convert carbon dioxide and water into
carbon compounds.
6. Heterotrophs
(p. 521)
organism that requires a constant supply of oxygen in order to live.
7. Photoautotrophs
(p. 521)
organism that cannot live in the presence of oxygen.
8. Chemoautotrophs
(p. 521)
organism, such as a bacterium, that can live in the absence as well as in the
presence of atmospheric oxygen.
9.Endospore (p. 521)
10. Bacteriaphage
(device)
11. Capsid (p. 526)
12. Vector
a vector is any agent (person, animal, or microorganism) that carries and
transmits an infectious pathogen into another living organism.]
