Anther and Filament of Stamen

Anther and Filament of Stamen

The stamen, also known as the thread of the warp, is the reproductive part of the flower which produces the pollen. They consist of a stalk called the filament “thread,” and an anther which contains microsporangia. Anthers usually have two lobes and they attach to the filament either at the base or at the mid portion. The tissue that can be found in between these structures is called connective tissue. Each microsporangium in the anther is lined by tapetum, a nutritive tissue layer; this contains the diploid pollen mother cells. Soon these cells undergo meiosis and become haploid spores; later the microspores become pollen grains that are ready to travel and take place in the reproduction cycle of plants.
