Study Notes
The Two Kingdoms
- In 1735, Carl Linnaeus categorized the living world into two kingdoms: Vegetabilia (plants) and Animalia (animals).
The Five Kingdoms
- In 1969, Robert Whittaker proposed a five-kingdom system that included Monera, Protista, Fungi, Plantae, and Animalia. This classification was based on differences in cellular structure, mode of nutrition, life cycle, and other characteristics.
The 2011 Census
- The 2011 census of life found a total of 1.9 million living species on Earth.
The Three Kingdoms
- In 1866, Ernst Haeckel proposed a three-kingdom system that included Protista, Plants, and Animals. This system was based on recognizing single-celled organisms as a distinct group.
Prokaryotes
- In 1925, Édouard Chatton created two groups of organisms Prokaryotes (without a nucleus) and Eukaryotes (with a nucleus). This classification was based on the presence or absence of a true nucleus in the cells.
