Flower petals are the colorful parts of a flower that attract pollinators like bees and butterflies. They come in various shapes, sizes, and colors, which help to signal to insects that nectar is available. Petals are often soft and delicate, forming a protective layer around the reproductive parts of the flower. The arrangement of petals can vary widely among different species. In some flowers, such as roses, petals are layered and tightly packed, while in others, like daisies, they are more spread out. The number of petals can also differ, with some flowers having just a few and others having many.
