Sexual reproduction in flowering plants
Sexual reproduction - 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.
Male gametes are found in pollen grains and produced in the anthers of the flower.
Female gametes are found in ovules and produced in the ovary of the flower.

| Sepals | Protect the unopened flower bud |
| Petals | May be brightly coloured and scented 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 (in ovules) |
| Nectary | May be present to produce sugary nectar to attract insects |
