Angiosperms belong to the class

Angiosperms belong to the class Spermatophyte. Angiosperms are flowering plants that produce seeds enclosed in an ovary (fruit). The class Spermatophyte includes all seed-bearing plants, both angiosperms and gymnosperms. Gymnosperms are a group of plants that produce seeds without an enclosing fruit, such as pine trees. Bryophytes and Pteridophytes are non-seed-bearing plants, while Thallophytes are a group of primitive, mostly unicellular or multicellular, plant-like organisms such as algae and fungi.
