Stigma and Style of a Carpel

The long stalk in the middle of this hibiscus flower is called a carpel. The carpel is another female reproductive organ found in the flower. It is comprised of two main parts called the stigma and style. On the hibiscus, the stigma is the the red tip of the central stalk. This is where pollen is received from pollinators. The rest of the stalk is the style. The style connect the stigma and the ovule to each other, sending down the male gametes within the pollen to fertilize the ovule.
