- The stigma is a swollen, knob-like structure. It can be either hairy or sticky, or sometimes both to trap pollen grains. In wind-pollinated flowers, like grasses, it may be feathery and branched or elongated. However, for some other flowers, it may be compact and has a sticky surface.

- The stigma is one portion of the female part of a flower. It is the top part of the pistil, followed by style and then ovary.
- The stigma is sticky and captures pollen to assist in the fertilization process. It also rehydrates the pollen and assist it moving down the style.
Jul 27, 2022 · Perfect flowers may be capable of self-pollination. Pollen produced within the flower may fall on a stigma in the same flower, and the sperm that it carries may fertilize the egg in the ovule. Sometimes, the timing of events during the stages of flower maturation encourage self-pollination.
The style emerges from the ovary and is topped by the stigma. Pollen grains land on the stigma and must grow a tube down the style to reach the ovule and complete fertilization. Figure \(\PageIndex{6}\): Here we see two sides of the same flower, which has been cut in half lengthwise.
Stigma is the part of a flower's pistil that receives pollen during fertilization. It plays a crucial role in the reproductive process by capturing pollen grains, which are essential for the fertilization of ovules.
A flower with both androecium and gynoecium — that is both male and female parts — is called perfect or bisexual or hermaphroditic. Perfect flowers may be capable of self-pollination. Pollen produced within the flower may fall on a stigma in the same flower, and the sperm that it carries may fertilize the egg in the ovule.
