Common Taxonomic Divisions. The scientific system of classification divides all living things into groups called taxa (singular, taxon). Plants are in the kingdom of Plantae. Other kingdoms include Fungi, Protista (one-celled organisms including yeasts, bacteria, and protozoans), and Animalia (animals).
Organisms are classified by cell type in the three domain systems. 1.
