What is difference between anther and filament?

The anther and the filament are the same because they are both part of the stamen. The stamen in a flower is the male reproductive organs.

Although these are both part of the Stamen, they both have a different function in the plant.

Filament: The stalk of the Anther.

Anther: Contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilised.
