Plants can be Dioecious

Some plant species are more like animals and each plant is either a male or a female. Plants with this situation are called dioecious. As with monoecious plants, flowers produced will have stamens but no pistils or pistils but no stamens. These male or female specific flowers, however, are made on separate plants, not on separate parts of the same plant.
