Gynoecium
/ɡaɪˈniːsiəm/
Definition
Gynoecium is the female reproductive structure of a flower. It consists of one or more carpels, which may be separate or fused, and includes the stigma, style, and ovary. The ovary contains the ovules, which can develop into seeds after fertilization, while the ovary itself may develop into fruit. This distinguishes the gynoecium from the androecium, the flower’s male reproductive part made of stamens.
Function in Plants
- Site of ovule development: It contains the ovules, which become seeds after fertilization. This makes it central to sexual reproduction and to the formation of the next plant generation.
- Fruit formation after pollination: After successful pollination and fertilization, part of gynoecium usually develops into fruit tissue. The structure of this tissue strongly affects how seeds are protected and dispersed.
- Key trait for flower identification: The number of carpels, whether they are fused, and the position of the ovary are major features used to identify flowering plants. These details also help botanists compare related groups.
- Linked to pollination strategy: Its shape and placement influence how pollen reaches the stigma and how pollen tubes grow toward the ovules. Differences often reflect adaptation to wind, insects, birds, or other pollinators.
