Theory Angiosperms: All flower bearing plants are called angiosperms. Monocot flowers are typically arranged in five whorls (carpels, inner and outer stamens, inner and outer tepals), and are radially symmetrical, constructed around a 3-fold axis of rotational symmetry that delineates three planes of bilateral symmetry. One of the most noticeable traits is that a monocot's flower is trimerous, with the flower parts in threes or in multiples of three. Leaves of the dicot contain a variety of shapes, but generally they are round in shape. Flowers are usually pentamerous i.e the floral parts are present in numbers of five; Seeds germination either hypogeal or epigeal.

Flowers are trimerous in the monocot and they are tetramerous and pentamerous in the dicot. Flower initiation occurred during the first growth stages of the buds. Monocots may have millions of individual Fibrous roots. The number of parts/chambers containing seeds also vary in number. Pentamerous flowers are formed by addition of a sector comprising a stamen and tepal. The basic difference between monocots and dicots, as their names suggest, is the presence of a single and double cotyledons respectively.

The categorization or classification of plants on this basis doesn’t have any fundamental concepts for support. . Instead, morphology of seed types is the only criterion being used in this kind of grouping. To put it simply, monocots have a single embryonic leaf, while the dicots have two of these. The classification of flowering plants has been made for a long time on the basis of number of cotyledons they possess, i.e., in the form monocot vs. dicot system of categorization.
