Fruits are ripened ovaries of flowers. The fruit is responsible for the dispersal and protection of seeds. The ovary of a flower is part of the pistil, the female reproductive organ. The ovary contains ovules, which when united with a pollen grain, forms a zygote. Above the ovary, pollen grains land on the stigma and grow down the style until it reaches the ovary. Ovules develop in a chamber known as a locule. Fertilization will take place in the ovary. Flowers with multiple carpels will also have multiple ovaries.
