The series of changes in the growth and development of an organism from its beginning as an independent life form to its mature state in which offspring are produced. In simple organisms, such as bacteria, the life cycle begins when an organism is produced by fission and ends when that organism in turn divides into two new ones. In more complex organisms, the life cycle starts with the fusion of reproductive cells and ends when that organism produces its own reproductive cells, which then may go on to reproduce.
