- In the system of classification used by most modern biologists, living things are organized into five kingdoms.
- The smallest kingdom, in terms of species so far indentified, is the Kingdom Monera, which contains bacteria – single-celled organisms that are the simplest forms of life.
- The Kingdom Protista also contains single-celled organisms, together with some multicellular algae, but their ells are larger and more complex than those of monerans.
- Most members of the Kingdom Fungi are multicellular, and live by absorbing organic matter from their surroundings.
- All plants, Kingdom Plantae, are multicellular, and live by photosynthesis. This large kingdom contains some 400,000 known species.
- All insects fall under Phylum Arthropoda of the Kingdom Animalia.
