angiosperm Any member of the phylum Angiospermophyta, comprising plants that produce flowers, fruits, and seeds. Angiosperms, of which about 250,000 species are known, include most herbs, shrubs, many trees, fruits, vegetables, and cereals. Their seeds are protected by an outer covering – the term "angiosperm" comes from the Greek aggeion for "vessel" and sperma for "seed". Angiosperms are further divided into two classes, monocotyledons and dicotyledons.
