| ovule | in seed plants, the female reproductive part that produces eggs |
| stamen | male reproductive organ inside the flower of an angiosperm; consists of an anther, where pollen grains form, and a filament |
| pistil | female reproductive organ inside the flower of an angiosperm; consists of a sticky stigma, where pollen grains land, and an ovary |
