Anther and filament of stamen
The stamen of a plant produces the pollen for pollination. Stamen are made up of a stalk and an anther (the stalk called the filament.) The anther contains microsporangia and is usually made up of two lobes. The microsporangia are sacs in the anther that form pollen through meiosis. The pollen is released during pollination and the opening of the anther. The filament is the stalk of the stamen and it serves to support the anther. The picture above is of a flower which has a stamen.
