what is petal in flower

Petal is a sterile floral part that usually functions as a visually conspicuous element of a flower. Petals are modified leaves and are often brightly colored to attract specific pollinators to the flower. They are usually accompanied by another set of modified leaves called sepals, that collectively form the calyx and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. Petals often come in multiples of three in monocots or in multiples of four or five in eudicots. Many horticultural flowers, such as roses and peonies, have been bred to have multiple layers of petals, resulting in showy textured blooms. The major function of petals is to attract insects and other pollinators to the flower.
