What is the difference between spermatophytes and bryophytes?

Spermatophytes are seed-producing plants that include gymnosperms and angiOSperms, while bryophytes are non-vascular plants like mosses, liverworts, and hornworts. Spermatophytes have seeds for reproduction and vascular tissues for water and nutrient transport, whereas bryophytes reproduce via spores and lack vascular tissues. Spermatophytes have a dominant sporophyte generation, while bryophytes have a dominant gametophyte generation.
