The pistil is the female reproductive part of a flower, and its main function is reproduction. It is typically located in the center of the flower and consists of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil, which is responsible for receiving the pollen. The style is a slender stalk that connects the stigma to the ovary, and it is responsible for safely transporting the compatible pollen to the ovule. The ovary is the enlarged basal portion of the pistil where ovules are produced, and it contains the potential seeds or ovules. During pollination, compatible pollen grains land on the stigma and then germinate, forming a pollen tube. The pollen tube grows down through the tissue of the style to deposit sperm for the fertilization of the ovules in the ovary. After fertilization, the ovary develops into a fruit, and the ovule develops into a seed. Therefore, the pistil plays a crucial role in the reproduction of flowering plants.
