| life cycle |
A continuum of phases and cell types in the reproduction and growth of a species. The life cycle usually contains at least an asexual phase in which a cell can divide by binary fission and produce two similar cells (1N). It may also contain a sexual phase in which gametes fuse to form zygotes (2N) and these zygotes produce 1N cells.
