From which part of the plant does pollen originate?

• A. Petal
• B. Stamen
• C. Ovary
• D. Sepal

Answer: (B)

Pollen originates from the stamen, which is the male reproductive part of a flower. The stamen is comprised of two main components: the anther and the filament. The anther is where pollen is produced and stored, while the filament supports the anther, positioning it to facilitate the transfer of pollen to pollinators or other flowers. Understanding the role of the stamen is crucial in the reproduction of flowering plants, as pollen plays a vital role in fertilization by transferring to the stigma of the female reproductive organ (the pistil), which typically includes the ovary. While petals and sepals are important for attracting pollinators and providing structure, they do not contribute to pollen production. The ovary, meanwhile, is involved in the development of seeds after fertilization but is not involved in the generation of pollen. Thus, the stamen is the essential component for pollen production in flowering plants, making it the correct answer.
