A stamen is the male reproductive part of a flower that consists of pollen sac (anther) and a long supporting filament. This filament holds the anther in position, making the pollen available for it to be dispersed by the wind, insects, or birds. The pollen grains are produced here by meiosis which is required for an angiosperm plant to reproduce. This picture shows the stamens clearly if you look at the inside of the yellow flower which looks like little rods with a small head tip on it.
