The ovule is a part of a flower that contains the female reproductive cells and develops into a seed when fertilized. It is located inside the portion of the flower called the gynoecium, which is the female reproductive organ of the flower. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Each ovule is attached by its base to the stalk (funiculus) that bears it. A mature ovule consists of a food tissue covered by one or two future seed coats, known as integuments. A small opening (the micropyle) in the integuments permits the pollen tube to enter and discharge its sperm nuclei into the embryo sac, a large oval cell in which fertilization and development occur.
In summary, the ovule is an essential part of the flower that contains the female reproductive cells and develops into a seed when fertilized. It is located inside the gynoecium and is attached to the stalk that bears it.
