virus: nonliving particle that invades and then reproduces inside a living cell
host: an organism that provides a source of energy or a suitable enviroment for a virus or another organism to live
parasite: an organism that lives on or in a host and causes harm to the host
bacteriophage: a virus that infects bacteria
bacteria: single-celled organism that lack a nucleus prokaryotes
cytoplasm: a region of a cell located inside the cell membrane in prokaryotes or between the cell membrane and nuclues in eukaryotes contains gel like material and cell structures
ribosome: a tiny structure located in the cytoplasm of the cell where proteins are produced
flagellum: a long whiplike structure that helps a cell to move
respiration: the exchange of gases between living cells and their environmnet includes breathing and cellular resperation
binary fission: a form of asexual reproduction in which one cell divides to form two identical cells
asexual reproduction: a reproductive process that involves only one parent and produces offspring that are identical to the parent
sexual reproduction: a reproductive process that involves two parents that combine their genetic material to produce a new organism which diiffers from both parents
conjugation: the process in which a unicellular organism transfers some of its genetic material to another unicellular organism
endospore: a small rounded thick-walled resting cell that forms inside a bacteria cell
pasteurization: a process of heating food to a temperature that is high enough to kill most harmful bacteria without changing the taste of the food
decomposer: an organism that breaks down chemicals from dead organisms and returns important materials to the soil and water
infectious disease: an illness that can pass from one organism to another
toxin: a poison that can harm an organism
antibiotic: a chemical that can kill bacteria without harming a persons cell
antibiotic resistance: the ability of bacteria to withstand the effects of an antibiotic
vaccine: a substance introduced into the body to stiimulate the production of chemicals that destroy specific diesease-causing viruses and organisms
