What are the two main types of angiosperms?

The two main types of angiosperms, which are flowering plants, are classified into monocots and dicots. Monocots, or monocotyledons, are characterized by seeds that have one cotyledon (the first leaf that appears during germination), parallel leaf venation, flower parts usually in multiples of three, and vascular tissue arranged in scattered bundles. Examples of monocots include grasses, lilies, and orchids.

In contrast, dicots, or dicotyledons, possess seeds with two cotyledons, usually have net-like leaf venation, flower parts often in multiples of four or five, and vascular tissue arranged in a ring. Common examples of dicots include roses, sunflowers, and oak trees. This classification is fundamental for understanding plant biology and biodiversity, as it highlights the vast diversity within angiosperms based on their structural and developmental traits.
