The ovule is a flowering plant organ that produces seeds. It is produced in the ovary of flowers and comprises a nucellus that is protected by seed coats, integuments and embryo/endosperm precursors, and seed coat.
In flowering plants, the ovule is known as the megasporangium.
It has an embryo sac that is made up of a functioning megaspore. The ovule is linked to the placenta by a funicle, which is a stalk.
The embryo sac is encased within the nucellus, which is then covered by integuments, which are protective coverings.
