In a flower’s anatomy there are three female parts: the stigma, the style, and the ovary. These three structures are collectively referred to as the carpel. The stigma is the topmost part of the carpel. Pollination occurs when pollen lands on the stigma. The stigma has a sticky quality which functions in trapping pollen. The style is the long stalk that connects the ovary and the stigma. After pollination, a tube grows through the style to transport the pollen from the stigma to the ovule so that fertilization can occur. You can observe the stigma and style of the carpel in the picture above.
