paragraph: Flowers have both male and female reproductive parts. The main parts of a flower are shown in Figure 3.21. They include the stamen, pistil, petals, and sepals. The stamen is the male reproductive structure of a flower. It consists of a stalk-like filament. At the end of the filament is the anther. The anther contains pollen sacs. It is here the pollen grains form. The filament raises the anther up high. This helps the pollen to be more likely to be carried away. It may blow in the wind. It may be picked up by an animal and carried away. Many animals are pollinators. A pollinator is any animal who carries the pollen from one plant to another. The pistil is the female reproductive structure of a flower. It consists of a stigma, style, and ovary. The stigma is raised. It is also sticky to help catch pollen. 
question: Does the stigma belong to the male or female reproductive organ?
answer: Female
