Retrieved October 30, 2014 from Encyclopedia.com: http://www.encyclopedia.com/doc/1G2-3400700159.html.Modern classification systems, based largely on molecular evidence, divide living organisms into three domains: Bacteria (also called Eubacteria), Archaea, and Eukarya. Plants are classified as a kingdom (Plantae) within the Eukarya; organisms that possess a nucleus, mitochondria, an internal cytoskeleton, and, in photosynthetic species, chloroplasts. Most scientists recognize three other eukaryotic kingdoms: Protista (most of which are single-celled organisms), Fungi, and
