In flowering plants, placentation is the attachment of ovules inside the ovary. The ovules inside a flower’s ovary (which later become the seeds inside a fruit) are attached via funiculi, the plant part equivalent to an umbilical cord. The part of the ovary where the funiculus attaches is referred to as the placenta.
