Anatomy. Monocot seed: a-Seedcoat, b-Endosperm, c-Cotyledon, d-Embryo. What seperates a monocot and a dicot is the number of cotyledons the plant has when it first breaks the surface. Monocots only have one, while dicots have two.1  Flowers: Monocots usually have three to six petals. 2  Pollen: Monocot's pollen usually have one pore in the outer layer.3  Stems: Monocots have vascular systems that are in long strands that are as far away from the center as possible.natomy.
