Stamens. A stamen is the general term for the male reproductive part of an angiosperm. Most flowers posses several of these upright structures, which consist of two main sections. The filament, or stalk, of the stamen stands vertical inside the flower petals.
Flowers, the reproductive organs of flowering plants, are the most remarkable feature distinguishing them from the other seed plants. Flowers provided angiosperms with the means to have a more species-specific breeding system, and hence a way to evolve more readily into different species without the risk of crossing back with related species.
