Explanation:

The flower is the reproductive organ of angiosperm plants. Flowers that have reproductive organs of both sexes, male and female, are called hermaphrodites (or monoecious).  Flowers that have reproductive organs of only one sex (male or female) are called dioecious.

A hermaphrodite flower is usually made up of four sets of modified leaves, the floral whorls. The whorls fit into a specialized branch called the floral receptacle. The four floral whorls are the chalice, consisting of the sepals, the corolla, consisting of the petals, the androceu, consisting of the stamens, and the gynoecium, consisting of the carpels.
