The female reproductive organ is the carpel: this contains an ovary with ovules (which contain female gametes).

The ovary contains one or more ovules, which in turn contain one female gametophyte, also referred to in angiosperms as the embryo sac. Some plants, such as cherry, have only a single ovary which produces two ovules.
