6. Both gymnosperms and angiosperms bear seeds, then why are they classified separately?
Both gymnosperms and angiosperms come under the group spermatophyta or seed-bearing plants. However, angiosperms and gymnosperms are classified separately in spermatophyta because gymnosperms possess naked seeds i.e. their seeds are not enclosed in ovary whereas angiosperms possess seeds that are enclosed in the ovary.
