What is the primary component of the pistil that works with the stigma?

The primary component of the pistil that works with the stigma is indeed the ovary. The pistil consists of three main parts: the stigma, style, and ovary. The stigma is the receptive surface where pollen lands and germinates, while the ovary is located at the base of the pistil and contains the ovules, which can develop into seeds upon fertilization. After pollen has successfully attached to the stigma, it travels down the style to the ovary, where fertilization occurs. This relationship is crucial in the process of reproduction in flowering plants, making the ovary an essential element that collaborates with the stigma in the reproductive cycle.
