When I was dissecting a disk flower, part of a composite flower (usually the yellow part of a daisy, etc), I observed it underneath a microscope and it was really hard for me to determine whether or not the disk flower has an ovar or even stamen. It was too tiny for me to see. If you know, by any chance, if the disk flower has a ovary and stamen(s)?
Do disk flowers have an ovary?
The Disk florets of composite flowers do have a fertile and inferior ovary and fertile stamens.
The stigma is usually bifid .
Anthers are united i.e. syngenesious.
After fertilization that ovary develops in to a fruit ; which is a dry fruit and called Cypsella in botany.
