The gynoecium is the female reproductive organ of angiosperms. It is made of one or more carpels.

Each carpel has three parts—stigma, style and ovary.

• Stigma: It is the sticky disc-shaped part of the gynoecium exposed to the environment. It is the receptive surface of pollen grains.
• Style: It is a long, slender tubular structure which connects the stigma to the ovary. When pollen grains germinate on the stigma, a pollen tube is formed through the style up to the ovary.
• Ovary: It is the enlarged basal part of the gynoecium which contains ovules. Ovules are attached to flattened, cushion-like placenta.
