Plant comparison. Artwork showing an example of each of the two subclasses of flowering plants: a dicotyledon (left) and monocotyledon (right). These names are derived from the number of leaves that cover the seed,which is two and one respectively. The root system of a dicotyledon consists of a primary (tap) root with smaller secondary roots. A monocotyledon has fibrous roots. The leaves of the dicotyledon are usually broad,bear small paired appendages (stipules) at the base of the leaf stalk and have a radiating vein structure. In comparison the monocotyledon leaf has parallel veins and is oblong in shape | |
