Sites of gamete production in flowering plants
Sexual reproduction in plants
In flowering plants, male and female reproductive structures can be found in the same individual plant. The organ of a sexual reproduction is the flower.
| Structure | Function |
| Sepals | Protect the unopened flower bud |
| Petals | May be brightly coloured to attract insects |
| Stamens | The male parts of the flower consisting of the anther held up on the filament |
| Anthers | Produce male gametes (in pollen grains) |
| Stigma | The top of the female part of the flower which collects pollen grains |
| Ovary | The bottom of the female part of the flower - produces the female gametes (ovules) |
| Nectary | May be present to produce sugary nectar to attract insects |
