No, apple trees are not monocots; they are dicots.
Apple trees (Malus domestica) belong to the Rosaceae family and are classified as dicotyledons, commonly known as dicots. This classification is based on the structure of their seeds, leaves, and other botanical characteristics. Unlike monocots, which typically have one seed leaf (cotyledon), dicots like apple trees have two seed leaves. Additionally, the leaf veins in dicots often form a branching pattern, while in monocots, the veins are usually parallel.
Furthermore, dicots tend to have floral parts in multiples of four or five, and their vascular system is organized in a ring pattern within the stem. These distinctive features are key differentiators that place apple trees firmly in the dicot category. In summary, apple trees exhibit all the characteristics of dicots, confirming that they are not monocots.
