About this topic

Flowers are the reproductive organs of angiosperms. The male stamen (anther and filament) makes pollen; the female carpel (stigma, style, ovary) contains ovules. Petals attract pollinators, sepals protect buds. Pollination is the transfer of pollen from anther to stigma, by insects (brightly coloured, scented flowers) or wind (small, feathery flowers).

After fertilisation, the ovule becomes a seed and the ovary a fruit. Cross-pollination increases genetic variety.

Insect-pollinated flowers have bright petals, scent and nectar, with sticky pollen, while wind-pollinated flowers like grasses have small dull petals, long stamens and feathery stigmas. After a pollen grain lands on a stigma, it grows a pollen tube down the style to the ovule, where fertilisation occurs. The ovule becomes the seed, and the ovary becomes the fruit.

Cross-pollination between plants increases variation, while self-pollination keeps the genes the same. Declines in bees threaten many crops, including apples and almonds. Students often confuse pollination with fertilisation: pollination is the transfer of pollen to the stigma; fertilisation is the fusion of nuclei, which may happen hours or days later.
