Specifically what organ in the flower causes it to emit scents.

Which part of the flower produces the aroma?
Any part of a plant has aromas, not just the flower, but the flower is the sexual stage of the plant and has to attract the help of the pollinators! But the most "famous and loved" aromas are found within the vacuoles within the cells of the cbeautifully olorful petals of flowering plants. These contain the most natural aromatic floral oils (which cause the aromas) that we can smell; aromas-scented oils were basically "designed by nature" to attract the birds-bees-pollinators; fruits produce aromas-aromatic oils too.(fruits are just pregnant flowers, the "swollen" ovaries of the stigma)
Reply:Mostly the petals.
Reply:Many flowers in nature have evolved to attract animals to pollinate the flower, the movements of the pollinating agent contributing to the opportunity for genetic recombinations within a dispersed plant population. Flowers that are insect-pollinated are called entomophilous (literally "insect-loving"). Flowers commonly have glands called nectaries on their various parts that attract these animals. Birds and bees are common pollinators: both having color vision, thus opting for "colorful" flowers. Some flowers have patterns, called nectar guides, that show pollinators where to look for nectar; they may be visible to us or only under ultraviolet light, which is visible to bees and some other insects. Flowers also attract pollinators by scent. Many of their scents are pleasant to our sense of smell, but not all. Some plants, such as Rafflesia, the titan arum, and the North American pawpaw (Asimina triloba), are pollinated by flies, so produce a scent imitating rotting meat.
