Detailed explanation-1: -Monocot maize has only one leaf inside the seed. Bean is dicot so it contains two leaves inside. Examples-apart from maize, corn also has the same characteristics. Beans contain a food sac for embryo feed.
Detailed explanation-2: -Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside the seed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant.
Detailed explanation-3: -The number of cotyledons (seed leaves) distinguishes whether a seed is a monocot or dicot. Monocots have one cotyledon and dicots have two. In most dicot seeds, the cotyledons store the food that the seed will use to grow until it gets its first true leaves and begins to make its own food.
Detailed explanation-4: -Cotyledon refers to the ‘first seed leaf’, present in the embryo. If it is a single seed leaf, then it is categorised as monocots and if it is a pair of leaves then it is categorised as dicots.
