The style is the tube-like structure that holds up the stigma. The style leads down to the ovary that contains the ovules. Other parts of the flower that are important are the petals and sepals. Petals attract pollinators and are usually the reason why we buy and enjoy flowers. The sepals are the green petal-like parts at the base of the flower.
Sepals help protect the developing bud.
Flowers can have either all male parts, all female parts, or a combination.
