Detailed explanation-1: -But, variations between monocots and dicots begin from the seed, which is the start of a plant’s life cycle. 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.

Detailed explanation-2: -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-3: -Monocot leaves are characterised by their parallel veins. All the veins originate at the base of the leaf and are parallel to each other in each lobe of the leaf, while dicots form “branching veins” also called reticulate venation.

Detailed explanation-4: -Taxonomy is a system for classifying plants based on their genetic and evolutionary relationship. Plant Taxonomy is a branch of science that continues to change as new species are being found almost every day. Plants are classified into a separate kingdom called the Kingdom Plantae.

Detailed explanation-5: -The main difference between monocotyledons and dicotyledons is that monocot contains a single cotyledon in its embryo whereas dicot contains two cotyledons in its embryo.
