The stigma is located at the top of the pistil. The stigma is sticky, and pollen attaches here.
The style is the long tube that attaches the stigma and the ovary. The sperm from the pollen travels down the style to the ovary.
The ovary is at the bottom of the pistil. The ovary produces and stores the egg.
The anther is located at the top of the stamen and produces the pollen.
The filament is the stalk, which supports and holds up the anther.
