cell - (biology) the basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals
culture - (biology) the growing of microorganisms in a nutrient medium (such as gelatin or agar); "the culture of cells in a Petri dish"
monad - (biology) a single-celled microorganism (especially a flagellate protozoan)
homogeny - (biology) similarity because of common evolution
heterology - (biology) the lack of correspondence of apparently similar body parts
valence, valency - (biology) a relative capacity to unite or react or interact as with antigens or a biological substrate
coarctation - (biology) a narrowing or constriction of a vessel or canal; especially a congenital narrowing of the aorta
