Plant Reproductive Structures. Plant sexual reproduction relies on stamens, which are the male parts, and pistils, which are the female parts. Stamens contribute the male genetic material in the form of pollen, which is produced from anthers that are on the terminal ends of stalks called filaments.ome plants donât form distinct petals and sepals, but they have one undifferentiated whorl comprised of structures called tepals. Petals, sepals, stamens and pistils are not formed on all flowers, but when they do the flower is said to be âcomplete.â.
