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.
The Monocots have only one seedling leaf (cotyledon) and usually have scattered vascular bundles, parallel veined leaves, and flower parts borne in multiples of three.hey have 6 tepals, usually 6 stamens, and three carpels fused into a superior ovary in typical monocot fashion, although the tepals are usually tiny and brown. The ovary, when mature in fruit, splits open as a capsule (sedges and grasses produce a single seed per flower).
