Many important crops need no insect pollination at all. The ten most important crops, comprising 60% of all human food energy, fall into this category: plantains are sterile and propagated by cuttings, as are cassava; potatoes, yams, and sweet potatoes are root vegetables propagated by tubers; soybeans are self-pollinated; and rice, wheat, sorghum, and maize, are wind-pollinated, as are most other grasses.
