Living organisms are divided into groups with similar characteristics, using the Linnean system of organisation, created in the 18th century by the Swedish botanist, Karl von Linne.
Living organisms are traditionally divided into the animal and plant kingdoms. Some biologists place the fungi, algae and many simple animals in a third kingdom called protista. Recently some biologists have placed the blue-green algae into a separate kingdom.
Each animal and plant belongs to a species and has a species name, which consists of two words in Latin. A species is a group of organisms that are similar to each other and can breed together. Each species belongs to a series of larger groups. A phylum is a main group and a class is a sub-group.
