The male reproductive organ of a flower is the

Step 1: Analyze the question The question asks which part of a flower is the male reproductive organ, the part that produces pollen (the male gametes).

Step 2: Explain the concept A complete flower has four main whorls, from outside to inside:

• Sepals (together called the calyx): green and leaf-like. They protect the flower bud.
• Petals (together called the corolla): usually colourful and scented. They attract insects for pollination.
• Stamens (together called the androecium): the male part. Each stamen has an anther, which produces pollen grains, and a filament, which supports the anther.
• Carpels (together called the gynoecium, or pistil): the female part. Each carpel has a stigma, style and ovary containing ovules.

Step 3: Solve by elimination

• A. Carpel: female reproductive organ. ✗
• B. Stamen: male reproductive organ (anther + filament). ✓
• C. Petal: attracts pollinators and is not directly involved in reproduction. ✗
• D. Sepal: protects the bud. ✗

Step 4: Answer The male reproductive organ of a flower is the stamen, which is option B.

Exam tip: Remember "STAMEN = MEN", since the word "stamen" contains "men". The carpel is the female part, as in "Carpel = Carries the eggs (ovules)". Questions like this often appear in JAMB and WASSCE, so learn the four whorls in order: sepals → petals → stamens → carpels.
