Location of ovules inside a Helleborus foetidus
Ovules produce the female reproductive cells which get fertilized during sexual reproduction in seed plants. The word literally means "small egg".[source?]
The megagametophyte (also called the embryo sac in flowering plants) is inside the ovule. The megagametophyte produces the egg cell.
