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. Pollination. Angiosperms have to undergo a process called pollination before they can reproduce. Angiosperms have male sex organs called stamens. On the end of the stamen is the anther.
