A scientist observes that some plants in a population of a newly-discovered species have increased reproductive success because they have extra floral whorls to produce pollen.Which floral parts have been duplicated in these individuals?

Question

Quizplus · Accepted Answer

Stamens are the floral whorl in angiosperms that produce pollen, so if a plant has extra stamens, it will have increased pollen production and therefore increased reproductive success. The other choices (pistils, carpels, sepals, and tepals) do not directly contribute to pollen production, so duplicating these structures would not necessarily increase reproductive success.
