The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops.

The word filament is from the Latin word filum, which means "thread." Filament, in fact, can be a synonym for thread. In an incandescent light bulb, a fine wire called a filament is heated to high temperatures in a bulb that lacks oxygen to prevent the filament from catching fire as it is heated. The filament begins to glow and gives off light. The first filaments were made from carbon, now they are usually made from tungsten because of its high melting point.
