The Five Kingdoms

Every organism on Earth belongs to a kingdom. Originally, there were only two kingdoms: Animalia and Plantae. The five kingdoms classification system was proposed by R. H. Whittaker in 1969.[4] The five kingdoms now recognized are Monera, Protista, Fungi, Plantae, and Animalia. Table 8-1 presents a composite of information about the five kingdoms based on the content of many of the Web sites (listed at the end of this chapter) we visited in our research.
