Floral structure refers to the arrangement and organization of parts within a flower. A typical flower consists of four main whorls: the sepals, petals, stamens, and carpels. The sepals protect the flower bud, while the colorful petals attract pollinators. Stamens are the male reproductive parts, producing pollen, and carpels are the female parts that contain the ovary. The arrangement of these parts can vary widely among different species, influencing how flowers attract pollinators and reproduce. Understanding floral structure is essential in fields like botany and agriculture, as it helps in the study of plant reproduction and the development of new plant varieties.
