1.
asexual reproduction: The reproductive process that involves only one parent and produces offspring that are identical to the parent
2.
bacteria: single-celled organisms that lack a nucleus; prokaryotes
3.
bacteriophage: A virus that infects the bacteria
4.
binary fission: a form of asexual reproduction in which one cell divides to form two identical cells
5.
conjugation: the process in which a unicellular organism transfers some of its genetic material to another unicellular organism
6.
cytoplasm: the region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus
7.
decomposer: an organism that breaks down chemicals from dead organisms and returns important materials to the soil and water
8.
endospore: A small, rounded, thick-walled, resting cell that forms inside a bacterial cell
9.
flagellum: long, whip-like structure that helps a cell to move
10.
host: An organism that provide a source of energy or a suitable enviroment for a virus or another or organism to live.
11.
infectious disease: An illness that can pass from one organism to another
12.
parasite: An organism that lives on or in a host and causes harm to the host.
13.
pasteurazation: a process of heating food to a temperature that is high enough to kill most harmful bacteria without changing the taste of food
14.
respiration: the process of braking down food to release its energy.
15.
ribosome: the process of breaking down food release its energy.
16.
sexual reproduction: A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents.
17.
virus: A tiny nonliving particle that invades and then reproduces inside a living cell.
