virus A tiny, nonliving particle that invades and then reproduces inside a living cell. host An organism that provides a source of energy or a suitable environment for a virus or another organism. A virus that infects bacteria. parasite An organism that lives on or in a host and causes harm to the host. bacteria bacteriophage cytoplasm Single-celled organisms that lack a nucleus; prokaryotes. ribosome The region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes); contains a gel-like material and cell structures. binary fission flagellum A tiny structure located in the cytoplasm of a cell where proteins are produced. asexual reproduction respiration A long, whiplike structure that helps a cell to move. The process of breaking down food to release its energy. A form of asexual reproduction in which one cell divides to form 2 identical cells. A reproductive process that involves only one parent and produces offspring that are identical to the parent. endospore sexual reproduction pasteurization conjugation decomposer A reproductive process that involves 2 parents that combine their genetic material to produce a new organism, which differs from both parents. An organism that breaks down chemicals from dead organisms and returns important materials to the soil and water. toxin The process by which a unicellular organism transfers some of its genetic material to another unicellular organism. A process of heating food to a temperature that is high enough to kill most harmful bacteria without changing the taste of the food. antibiotic A small, rounded, thick-walled, resting cell that forms inside a bacterial cell. infectious disease antibiotic resistance FROM BACTERIA TO PLANTS vaccine A chemical that can kill bacteria without harming a person’s cells. CHAPTER 2 SECTIONS 2.1 – 2.3 FLASHCARDS An illness that can pass from one organism to another. A poison that can harm an organism. The ability of bacteria to withstand the effects of an antibiotic. A substance introduced into the body to stimulate the production of chemicals that destroy specific disease-causing viruses and organisms.
