A monocot is a type of flowering plant that is characterized by having a single cotyledon, trimerous flowers, and parallel leaf veins. Monocots are economically important as food sources for both humans and animals, and they grow in a variety of habitats, including the tropics.
Economically, monocots are perhaps the most important organisms on earth. Our four most important foods -- corn, rice, wheat, and barley -- all come from monocots.
