Answer: D, In flowering plants, the reproductive organs are the pistil and stamen.

Key Takeaway: The female reproductive organ is the pistil, and the male reproductive organ is the stamen. The pistil houses the ovules, the female gametes, in the ovary and the stamen houses pollen, the male gamete. A major distinguishing feature of flowering plants is the process of double fertilization, in which an angiosperm ovule contains both an egg cell and a diploid fusion nucleus.
