Q. What are the major morphological differences between monocot plants and dicot plants?

The main separation criteria between monocots and dicots are: number of cotyledons (seed leaf) in seeds, one in monocots and two in dicots; pattern of leaf veins, parallel in monocots, reticulated in dicots; multiplicity of petal number, multiples of three in monocots, multiples of four or five in dicots; position of vascular bundles in the stem, scattered in monocots, concentrically ringed in dicots. Grasses, sugar cane, banana tree, orchids are instances of monocots. Oaks, Sunflowers and waterlilies are examples of dicots.
