Classification of Angiosperms
Based on the types of cotyledon present, angiosperms are divided into two classes. They are monocotyledons and dicotyledons. The dicotyledonous angiosperms have two cotyledons in their seeds and the monocotyledonous angiosperms have one cotyledon.
Monocotyledonous plants
The monocots have some distinct features that include the presence of adventitious roots, simple leaves with parallel venation, and trimerous flowers. The number of vascular bundles is more and is closed. Some of the examples include bamboos, sugarcane plants, banana, cereals, lilies etc.
Dicotyledonous plants
The dicotyledonous plants have two cotyledons with a tap root system. The venation seen in the leaves is reticulate. Flowers can be tetramerous or pentamerous. Vascular bundles are generally arranged in a ring and number between two to six. Examples include Grapes, Dandelions, Sunflower, Tomatoes, and Potatoes etc.
