Pistils are the female part of a flower's reproductive system. Synonyms for pistils include: carpels, gynoecium, ovary, style, and stigma. Carpels refer to the female reproductive organ of a flower, while gynoecium represents the collective pistils in a specific flower. The ovary is the enlarged basal portion of the pistil and contains ovules, which develop into seeds when fertilized. The style is the thin, elongated portion of the pistil that connects the ovary to the stigma, which is the receptive surface for pollen. Knowing the synonyms for pistils is important in order to understand the different parts of flower anatomy and their functions in plant reproduction.
