Which of the following is the male reproductive organ in plants?

The correct answer is Stamen.

Key Points

• The stamen is the male reproductive organ in flowering plants, responsible for producing pollen.
• It consists of two main parts: anther (which produces pollen) and filament (a stalk that supports the anther).
• Pollen grains produced by the anther contain male gametes required for fertilization.
• Stamens are collectively known as the androecium, which is the male reproductive whorl of the flower.
• The number and arrangement of stamens vary across different species of flowering plants.

Additional Information

• Pistil: The female reproductive organ in plants, consisting of stigma, style, and ovary.
• Pollination: The transfer of pollen grains from anther to stigma, enabling fertilization.
• Fertilization: The process where male and female gametes fuse to form a zygote, leading to seed formation.
• Complete Flower: A flower that contains all four floral whorls: sepals, petals, stamens, and pistils.
• Unisexual Flower: A flower that contains only stamens (male) or pistils (female), but not both.
