What is the anther of a flower for?
The anther produces pollen (male reproductive cells) . The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it.
