Answer:
Flowers are not on plants just to make them look pretty. They are there as a vital part of a flowering plant’s life cycle. Not all plants have flowers, find out what flowering plants are and how they are different to other plants.
Harakeke flowers
Harakeke has colourful flowers with lots of nectar to attract birds such as tūī. There is no pollen left on the dark anthers of these flowers.
Flowering plants create seeds, which get spread away from the parents and grow into new plants in new places. These seeds are part of the sexual reproduction of flowering plants. In this process, male cells combine with female cells, either on the same plant, leading to self-pollination, or between two plants of the same species, called cross-pollination.
Flowers have male and female structures, and it is the process of pollination that transfers pollen from the male part to the female part. After pollination, pollen releases a male gamete that fertilises a female gamete in the ovule and mixes their genetic material. After this fertilisation, the ovule grows to form a seed. This pollination and fertilisation article has more information.

Pollination has to happen before seeds can be made, so flowers have a range of ways to make sure it does. The male pollen cannot move to the female part of a flower on its own, so wind and animals are used to carry it instead. All the colours, shapes, sizes and smells of flowers are their ways of making it easy for the wind or animals to pick up and carry the pollen to the right female flower part.
