361654403Describe a Monocot.One cotyledon, veins usually parallel, vascular bundles in complex arrangement, floral parts are usually in multiples of three, and fibrus root system.
361654404Describe a Dicot.Two cotyledons, veins usually branched, vascular bundles arranged in ring, floral parts usually in multiples of four or five, and taproot usually present.
