U. of Wisconsin Angiosperms Think of how different our world would be if flowering plants had never evolved. Imagine a spring without those lovely monocots, the flowering bulbs. There would be no fruit, no grains, no need for pollinating insects, no perfumes, and few textile sources. This short segment of a long list is ample illustration of the vast importance of angiosperms in our lives. The flower is the main reproductive center of the angiosperm.
Some angiosperms produce only one type of gametophyte, either male or female, per plant.
They are thus termed dioecious, and these plants are either male or female. An example of this type of plant is holly. Others, which are monoecious, produce male and female gametophytes on different flowers of the same plant. The last type has both male and female parts in a single flower. You can see their differences illustrated on the chart at this station.
