life cycle

the serial progression of stages through which an organism passes from FERTILIZATION to the stage producing the GAMETES. In higher animals and plants the life cycle lasts from fertilization until the resulting individual itself produces gametes, but in many organisms there are asexual stages. see ALTERNATION OF GENERATIONS.
