Scientific definitions for angiosperm
Any of a large group of plants that produce flowers. They develop seeds from ovules contained in ovaries, and the seeds are enclosed by fruits which develop from carpels. They are also distinguished by the process of double fertilization. The majority of angiosperms belong to two large classes: monocotyledons and eudicotyledons. The angiosperms are the largest phylum of living plants, existing in some 235,000 species. They range from small floating plants only one millimeter (0.04 inch) in length to towering trees that are over 100 meters (328 ft) tall. Compare gymnosperm.
