In connection with the appearance of the first plants on land, they appeared …

The plants that first appeared on land began to grow flowers. Flowers did not make sense in water, since pollen could not spread in water. But on land it was much easier. The pollen is produced by the stamens. The first flowering plants were wind-pollinated. When pollinating insects appeared, the flowers began to adapt and received colored pigments in the petals so that the flowers were visible from a height for insects, as they stand out against the background of soil, foliage and other flowering plants.
