This is a picture of the stigma and style of carpel. The carpel is the innermost part of a flower and is the female reproductive structure. A carpel is made up of the stigma, the style, and the ovary. The stigma is the top portion of the carpel and is where pollination usually occurs. The style is a long tube that connects the stigma to the ovary. Pollen grains will then produce pollen tubes down the style toward the ovary and release sperm cells.
