There are many distinguishing characteristics between monocot and dicot angiosperms. For one, monocots have only one cotyledon inside of the embryo while dicots have two. Secondly, the roots of monocots are fibrous. The vascular tissue inside of the stems of monocots is scattered. There is one opening for inside of the pollen grains of monocots and the leaves are usually parallel. And lastly, the petals of the flowers are arranged in multiples of three’s like in the picture of the monocot above.
