Pollen Production in Flower Anatomy

Steps:

• Recall the male reproductive part of a flower is the stamen, consisting of anther and filament.
• Identify that pollen grains form in the male gametophyte within the flower's structure.
• Match the function: the site of pollen production is the anther's pollen sacs.
• Confirm by eliminating female parts like stigma and style, which are involved in pollen reception.

Why A is correct:

• The anther is the pollen-producing organ in the stamen, where microsporangia develop pollen grains via meiosis.

Why the others are wrong:

• B. Filament: Supports the anther but does not produce pollen.
• C. Stigma: Receives and collects pollen during pollination.
• D. Style: Transports pollen from stigma to ovary after landing.

Final answer: A
