The number of seed leaves their embryos have is the basis of their classification into monocots and dicots.
Michael Frohlich's research on Corystospermales supports the view that the structure of these organisms comes mainly from their male reproductive organs, the "mostly male" hypothesis. Recent research on their origins has discredited the hypothesis that Gnetales are closest to these organisms, but both groups undergo a process in which a tube penetrates the micropyle and two sperm cells enter the female gametophyte called double fertilization. A structure belonging to these plants forms when the walls of their ovaries thicken to become (*) pericarp. The number of seed leaves their embryos have is the basis of their classification into monocots and dicots. Their reproductive organs include carpels containing the stigma, style, and ovary, and the stamen, which has a filament and an anther. For 10 points, name this group of plants which have fruit and flowers, unlike gymnosperms.
