Spermatophyte is a scientific term used to describe a type of plant that produces seeds. To simplify this term, there are a few alternative synonyms that can be used. For instance, seed-bearing plants, phanerogams, and tracheophytes are synonyms for spermatophytes. These terms describe plants that have evolved the ability to disperse seeds, which evolved from the ancestors of ferns and horsetails that lacked this ability. Seed-bearing plants are classified into two major groups, namely gymnosperms and angiosperms. Gymnosperms, such as pine and spruce trees, have seeds that are not enclosed within fruits, while angiosperms have seeds enclosed within fruits, like apples and oranges.
