Description : The floral part that produces pollen grains is (1) Sepal (2) Petal (3) Anther (4) Ovary
Last Answer : (3) Anther Explanation: The anther contains microsporangia. Each microsporangium contains pollen mother cells. These undergo meiosis, and produce pollen grains, which contain the male gametes (sperm). The pollen is released by the opening of the anther.
