What is the significance of the flower for angiosperms?

Flowers are essential for angiosperms. From a pollinated flower, or rather from a pollinated pistil, the fruit of a plant is formed. All other parts of the flower take an important part in this. The stamens produce pollen for pollination. The pistil is pollinated with pollen. The petals have two functions at once. This is a protective function, since they are able to close and protect pollen from weathering and washout by rain, as well as the function of attracting pollinating insects. Insects see a multi-colored flower from a great height against a background of leaves and soil.
