A stamen is defined as the male reproductive organ of a flower. It is responsible for the production of pollen grains. The morphological studies of stamen show that it consists of a stalk that is known as filament and to this, an anther is being attached. The anther holds microsporangia in it.
The pollen grains are developed from the microspores which are present inside the microsporangia and they have the male gametophyte. The stamens group together to form androecium. The androecium is responsible for creating diverse patterns in several species of plants. The gynoecium which is the female part of the flower is being surrounded by it.
