The male gametophyte is the pollen grain. Pollen is produced from the anthers, located on the stamen. The female gametophyte is found within the ovules which are inside the ovary of the angiosperm, usually located at the base of the pistil. After fertilization, the ovary becomes the fuit and the ovules become the seeds. Members of the aster family of angiosperm have a composite of two different kinds of flowers.
Daisies are from the aster family.
Disk flowers are the smaller ones in the center.
