Angiosperms and gymnosperms belong to the class Spermatophyta. Spermatophyta is a group of plants that reproduce by producing seeds. This class includes two major divisions, gymnosperms and angiosperms. Gymnosperms are plants that have seeds without any protective covering or fruit, while angiosperms are plants that have seeds enclosed in a fruit. Both of these divisions are further divided into various families and species.
