Flowers reproduce when pollen from the male stamen fertilizes the female organ, which is called the carpel. All flowering plants have both male and female reproductive organs.
The stamen of a flower is made up of two parts: The filament and the anther. Pollen grains are found on the anther, which is at the end of the filament. This stamen is located inside the flower's corolla, formed by the petals.
The carpel, or female reproductive organ, is located in the center of the corolla. The carpel is comprised of three separate parts: The stigma, style, and ovary. Pollen from the male stamen fertilizes the female carpel.
