The stigma and style of carpel is not shown in this picture but it
is located inside the center of the flower. They are both parts of the pistil,
which is a female part. The style is the long tube like structure that is
connected to the ovary of the flower. It is the connective tissue of stigma and
the ovary. The stigma is a sticky, flattened knob attached on the top of the
style. Pollen grains land on the sticky stigma and germinate. When it
germinates, it creates pollen tubes then travels down the style into the ovary.
Fertilization occurs in the ovary after the pollen reaches it.
