👉 Stamens are structures that form on the stigma of flower petals. The stigma is a protective covering over the female reproductive part of a flower, and it contains the pollen grains for fertilization. In plants, the primary function of the stigma is to protect the pollen grains from being eaten by insects or other animals, while also allowing the pollen to fall down into the ovary of the flower. The stigma also helps in attracting pollinators like bees and butterflies to the flowers. Stamens
