---|---|
organism | a living thing |
cell | the basic unit of structure and function in an organism |
unicellular | a single celled organism |
multicellular | an organism composed of many cells |
autotroph | an organism that makes it's own food |
heterotroph | an organism that cannot make it's own food |
homeostasis | the maintenance of stable conditions |
classification | kingdom, phylum, class, order, family, genus, species, |
taxonomy | the scientific study of how living things are classified |
binomial nomenclature | the naming system Linnaeus used |
virus | a tiny, nonliving particle that enters and then reproduces inside a living cell |
host | an organism that provides a source of energy for another organism |
parasite | an organism that lives in or on a host and causes it harm |
bacteriophage | a virus that infects bacteria |
bacteria | single celled organisms, prokaryotes, genetic material is not contained by nucleus |
flagellum | a long, whip like structure that helps a cell move |
binary fission | bacteria's way of reproduction; one cell divides into two identical cells |
conjugation | one of the way bacteria reproduces, when bacterium transfers genetic material into another bacterium through a thin bridge |
endospore | small, rounded, thick-walled, resting cell that forms inside a bacterial cell |
eukaryote | cells that have a nucleus |
prokaryote | cells that have a nucleus |
nucleus | the "center" that controls the cells |
infectious diseases | illnesses that pass from one organism to another |
antibiotic resistance | results when some bacteria are able to survive in the presence of an antibiotic |
vaccine | a substance introduced into the body to stimulate the production of chemicals that destroy specific viruses or bacteria |
symbiosis | a close relationship in which at least one of the species benefits |
protist | eukaryotes that cannot be classified as animals, plants, or fungi |
cilia | hairlike projections that move with a wave-like motion |
protozoan | animal-like protists |
psuedopod | temporary bulges of the cell |
algae | plantlike protists |
algal bloom | rapid growth of a population of algae |
fungi | eukaryotes that have cell wall, are heterotrophs that feed by absorbing their food, and use spores to reproduce |
hyphae | the branching, threadlike tubes that make up bodies of multicellular fungi |
fruiting bodies | reproductive structures in which fungi produce spore |
budding | a form of asexual reproduction in which no spores are produced, and instead a small yeast cell grows from the body of a parent cell, then breaks away and lives on its own |
