DictionarySeelinearexponential growth
exponential growth[‚ek·spə′nen·chəl ′grōth] (microbiology) The period of bacterial growth during which cells divide at a constant rate. Also known as logarithmic growth. (science and technology) The increase of a quantity x with time t according to the equation x = Ka t , where K and a are constants, a is greater than 1, and K is greater than 0. exponential growth change in a variable (e.g. population – see MALTHUS) where the increase is geometric, i.e. at an increasing ratio.exponential growthExtremely fast growth. On a chart, the line curves up rather than being straight. Contrast with linear.exponential growth
log·a·rith·mic phaseexponential, a period in the course of growth of a bacterial culture in which maximal multiplication is occurring by geometric progression; thus, if the logarithms of their numbers are plotted against time, they will form a straight upward line. |
