A
leaf veins resemble a net of web
B
leaf veins are parallel
C
Fibrous root system
D
flowers in multiples of three
Explanation: 

Detailed explanation-1: -Typically, dicot leaves either have more stomata on the lower side of the leaf, or they have stomata only on the lower side of the leaf. Leaves with stomata only on the lower side are known as hypostomatous leaves. This arrangement of stomata allows dicot leaves to conserve water.

Detailed explanation-2: -The dicot leaf is characterized by its unique net vein orientation, which is unlike monocots who have a parallel venation or a pine needle which have no veins at all. Dicots also have an extra tissue layer known as the palisade parenchyma.

Detailed explanation-3: -Monocot leaves tend to have parallel veins; in dicots the veins are netted. Monocot floral parts are in multiples of 3; dicots are based on 4’s or 5’s. The vascular bundles in monocots stems are scattered; in dicots they form a ring surrounding the pith.

Detailed explanation-4: -In dicots, venation is netted, that is the main vein divides into various branches and make a net like structure in the lamina.
