Flowers are often brightly colored in order to attract attention from insects, such as bees, that pollinate the flowers. Most insects that are necessary for the pollination process can see color, and the different colored flowers typically act as signals to notify insects that they are ready. The colors of flowers depend on the region and climate they primarily live in.
Pollination is the reproductive process in plants and flowers. It is a necessary step in order for reproduction to occur, as the pollen of the plant is taken from the male part, the anther, to the female part, the stigma, of the flower. If successful, pollination allows the plant or flower to produce fruit, which can then be used to spread its seeds.
