The below mentioned article provides study notes on Dicots and Monocots.
Angiosperms are divided into two subgroups, dicotyledonous and monocotyledonous plants, mainly on the basis of number of embryonic leaves or cotyledons. The two are commonly spoken as dicots and monocots.
Dicots:
They are angiospermic or flowering plants which are characterised by the presence of two cotyledons in the seed, generally reticulate venation in leaves (with a few exceptions), concentric tissues in the stem with open vascular bundles arranged in a ring, penta- or tetramerous flowers e.g., Pea, Rose, Eucalyptus, Mustard, Cotton, Acacia, Sunflower. The number of dicot species is over 200,000.
Monocots:
They are angiospermic or flowering plants which are characterised by the presence of a single cotyledon in the seed, generally parallel venation in the leaves (exception Smilax, Colocasia and relatives), scattered closed vascular bundles in the stem and trimerous flowers, e.g., Banana, Cereals, Palms, Grasses, Bamboo, Lilies, Orchids. About 50,000 species of monocots are known.
