Schizophyte was a botanical classification proposed by Ferdinand Cohn to describe the class of primitive "plants" that reproduce solely by fission.[1] It has been considered synonymous with the Protophyta of Sachs and the Monera of Haeckel.[2] In modern taxonomy, it is equivalent with the concept of prokaryotes, single-celled microorganisms with no nucleus or other membrane-bound organelles, now divided into the domains Bacteria and Archaea.
