<human>:  Why do plants have flowers?
<bot>: Flowers are the reproductive organs of plants. They are adapted to attract pollinators. Flowers are made up of three parts: the sepals, the petals, and the stamens. The sepals protect the flower from rain and other damage. The petals are the colorful part of the flower, and the stamens produce pollen. Pollen is the male gamete, and it is carried by the wind to fertilize the female gamete, the ovum.
