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 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 |
| Ovule | Produces the female gametes |
| Nectary | May be present to produce sugary nectar to attract insects |
