In biology, a kingdom is the top-level, or nearly the top-level, grouping of organisms in scientific classification. Originally, two kingdoms were distinguished, the Animalia (animals), which typically could move about, and the Plantae (plants), which typically could not.
Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. chlorophytes and rhodophytes), the Kingdom Chromista (e.g. phaeophytes, dinoflagellates, diatoms), the Kingdom Protista (e.g. Euglenophytes), and the Kingdom Bacteria (cyanophytes).olecular phylogeny (gene sequencing) and other characters show they belong to three kingdoms: Kingdom Plantae (chlorophytes and rhodophytes), the Kingdom Chromista (phaeophytes), and the Kingdom Bacteria (cyanophytes).
