Class Dicotyledones, also known as dicots, is a classification of flowering plants (angiosperms) that have two embryonic seed leaves or cotyledons during their initial stage of development. This class of plants usually have features such as leaves with net-like veins, flower parts in multiples of four or five, and the presence of a main root. Examples of Dicotyledones include roses, sunflowers, and apple trees. This class has now been largely replaced in modern classification by the clade Eudicots, though some botanists still use the Dicotyledones categorization.
