The whorls that make up a complete flower are the calyx, corolla, androecium, and gynoecium.
1. Calyx: The calyx is the outermost whorl of the flower and is usually green in color. The main function of the calyx is to protect the developing flower bud. It consists of a series of sepals, which are modified leaves that enclose and protect the flower bud before it opens.
2. Corolla: The corolla is the second whorl of the flower and is located inside the calyx. It is typically brightly colored and consists of a series of petals, which are also modified leaves. The main function of the corolla is to attract pollinators to the flower. The bright colors and attractive shapes of the petals help to lure bees, butterflies, and other insects to the flower, where they can collect pollen and thus aid in the process of pollination.
3. Androecium: The androecium is the third whorl of the flower and comprises all of the male reproductive structures. It consists of one or more stamens, each of which is composed of a filament and an anther. The filament is a thin, elongated structure that supports the anther, which is the site of pollen production. The main function of the androecium is to produce and release pollen, which can then be transported to other flowers by pollinators.
4. Gynoecium: The gynoecium is the innermost whorl of the flower and contains all of the female reproductive structures. It consists of one or more carpels, each of which is composed of an ovary, a style and a stigma. The ovary is the female reproductive organ where the ovules, which later become seeds, are produced. The style is a long, slender structure that supports the stigma, which is the receptive surface for pollen. The main function of the gynoecium is to receive and fertilize pollen, leading to the formation of seeds and fruit.
