Submit. The term angiosperm is used to identify all the flowering plants in the world. As a flowering plant, the water lily (Nymphaeaceae) is an angiosperm. About 80 percent of all the plants on earth are angiosperms.
Angiosperms are vascular plants. They have stems, roots, and leaves. Unlike gymnosperms such as conifers and cycads, angiosperm's seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower.The flowers of angiosperms have male or female reproductive organs.hese angiosperms start with one seed-leaf. The main veins of their leaves are usually unbranched. There are about 30,000 species of monocots. Monocots include orchids, lilies, irises, palms, grasses, and grains like wheat, corn and oats. Fruits like dates and bananas also belong to this group.
