The main difference between monocots and dicots is the number of cotyledons.
Step-by-step explanation:
In case, monocots change from dicots in four fundamental features: their leaves, stems, roots, and flowers. Inside the seed occupies the plant's embryo; it is here that the primary distinction between the two types can be seen. Whereas monocots have one cotyledon (vein), dicots have two. monocots begin out with one seed leaf, while dicots have two.
