On our planet earth, there are five kingdoms, that consist of many living things. Using the five kingdoms we classify our species and organize information on what we are and what resides with us. When we organize every living creature in the five kingdoms it helps us better understand the habitants of the world around us. The five kingdoms are Moneran, Protist, Fungi, Plantae, and the one we belong to, animalia.
The Moneran kingdom is the bacteria. There are basically two types: Eubacteria and Archaebacteria. Eubacteria is called the "true bacteria" which are the majority of 10,000 species in the Moneran group. Archaebacteria are the ancient bacteria. Being the minority of the Moneran group they are only found in extreme environments such as swamps, salt lakes, and deep-ocean hydrothermal vents. Many species of the Moneran kingdom are yet to be discovered. Monerans are also the only group in the five kingdoms that are all prokaryotes. Prokaryotes are one-celled or colony of cells. Its cell structure has no nucleus, no organelles, a cell membrane, and some cell walls. They can obtain food by photosynthesis, decomposition, or from being parasites. Its movement method is in water or in host.
The Protist Kingdom is basically all the multi cellular organism which don't fit into the Animal, Plant, or Fungus Kingdom. At first, protozoa were placed in a subkingdom of Animalia. This classification had problems. Some forms showed mixed characteristics, and some groups had members that were plant like with close relatives that were animal like. Eventually a five-kingdom system came into use, in which Plantae and Animalia are more restricted in definition and protozoan groups are assigned to the kingdom protista. .
This Kingdom contains from 20 to 50 distinct Phyla. With the exception of the larger Algae(seaweeds and kelp) Protists are pretty much all microscopic organisms. The Kingdom Protista include the one-celled or multi celled heterotrophs (protozoa); eukaryotic algae, including some that are multi cellular; and slime molds.
