Plant biologist use the term division for the major plant groups within the plant kingdom. The taxonomic category corresponds to phylum, the highest unit of classification within the animal kingdom. Divisions, like phyla, are further subdivided into classes, order, families and genera. The classification scheme used in this book recognizes two main groups called bryophyta (non vascular plants) and tracheophyta (vascular plants) This division is based on the presence or absence of vascular tissues.
