The vast majority of flowering plants have male and female parts on the same flower.
Some flowering plants have separate male and female flowers on the same plant (monoecious); e.g., Mexican Blue Oak (Quercus oblongifolia).
And some flowering plants have male flowers and female flowers on separate plants (dioecious).
Let's look at some dioecious plants (and their fruits).
