A typical flower has four different kinds of whorls, arranged successively on the swollen end of the stalk, which is called the receptacle. These four whorls are:

1. Calyx: This is the outermost whorl of the flower. It is usually green and consists of sepals. The main function of the calyx is to protect the flower bud.

2. Corolla: This is the second whorl, located just inside the calyx. It consists of petals, which are usually brightly colored to attract pollinators.

3. Androecium: This is the third whorl, consisting of stamens. Each stamen has a filament and an anther, where pollen is produced.

4. Gynoecium: This is the innermost whorl of the flower, consisting of one or more carpels. Each carpel includes an ovary, style, and stigma. The ovary contains the ovules, which can develop into seeds after fertilization.
