DescriptionThe Magnoliophyta is the largest plant group on Earth, containing more than 250,000 described species. The Magnoliophyta is subdivided into two classes, Liliopsida (monocots) and Magnoliopsida (dicots). Plants in this division are also termed the Angiosperms, or flowering plants. They have leaves, stems, roots, and vascular tissue (xylem and phloem). The ovules develop into seeds and are enclosed within an ovary, thus the term angiosperm, meaning "enclosed seed". The flowering plants include all cereal grains, grasses, broad-leaved shrubs and trees and most ornamentals.
