what characteristics are used to distinguish between the organisms in different kingdoms
The primal difference between kingdom and domain is that the kingdom is one of the five major groups of living organisms while the domain is one of the three taxonomic categories of living organisms above the kingdom level.
There were many attempts of classification of organisms on earth. Till 1977, kingdom system was universally accepted across the earth. Starting from the two kingdoms system called the Linnaean system way back in 1758 when the life forms were divided into plants and animals, the globe has come to recognize the three-domain system as the most current and the most scientific arrangement of classification of organisms. Though in that location are some similarities, the kingdom organization of classification of organisms has now been relegated to having relatively little significance since the 3-domain organization popularized in all parts of the earth. The aim of this article is to find out the difference between kingdom and domain system of nomenclature of organisms.

What is Kingdom?
The old ii-kingdom system of classification comprised of two kingdoms; institute kingdom and animate being kingdom. A Linnaean system called all organisms that moved with anima (with a soul), and fungi got classified as plants. The organisation went on calculation kingdoms. However, the five-kingdom classification system was believed to exist the complete organisation after the discovery of bacteria, algae and electron microscope.

Hence, the five-kingdom nomenclature proposed in 1969, is the most updated arrangement of classification today even though the six-kingdom classification is more accurate. Plantae, Archaebacteria, Eubacteria, Protista, Animalia, and Fungi are the half dozen-kingdom included in the six-kingdom nomenclature. In this nomenclature system, the fifth kingdom; Monera has been divided into Archaebacteria and Eubacteria; thus, bringing the number of kingdoms to six. Five kingdom nomenclature includes 5 kingdoms namely Monera, Protista, Fungi, Plantae and Animalia. In all classifications, whether 5 or 6 kingdoms, a kingdom has subdivision such every bit phyla or divisions. In fact, Kingdom Animalia consists of phyla while the Kingdom Plantae has divisions.
What is Domain?
Two scientists, Woese and Wolfe, in 1977, completely changed the organisation of classification of organisms in the earth when they made utilise of 165 ribosomal RNA sequences. Till 1977, the world had come up to take the bifurcation of life forms into eukaryotes and prokaryotes. Simply information technology was the discovery of archaea; the microorganism that could alive without oxygen, and then reminded one of the ancient surround of world that was devoid of oxygen, that forced scientists to conceive of a 3rd category of organisms.

Therefore, Archaea was accepted as being different from the earlier two classifications, and thus the three-domain system came into beingness. Appropriately, the three domains include Bacteria, Archaea and Eukarya.
What are the Similarities Between Kingdom and Domain?
- Kingdom and domain are two types of categories to classify living organisms.
- Kingdoms are coming under the domains.
- All living organisms vest to 3 domains as well every bit to five kingdoms.
What is the Difference Between Kingdom and Domain?
Three domains or five kingdoms are two types of nomenclature systems to categorise living organisms. The key difference between kingdom and domain is that the kingdom is one of the five major groups of living organisms while the domain is one of the three taxonomic categories of living organisms above the kingdom level. Thus, domain is a category above the kingdom level. Accordingly, there are three domains namely bacteria, archaea and eukarya. On the other manus, the kingdom is a major category of living organisms below the domain level. There are five kingdoms namely monera, protista, fungi, plantae and animalia. Hence, this is another deviation between kingdom and domain.
Summary – Kingdom vs Domain
Classification of living organisms is important to place and study their characteristics and phylogenetic relationships. Classification systems include dissimilar hierarchical levels. Among the different hierarchical levels, domain and kingdom are ii chief levels. Accordingly, domain is a category above the kingdom level. In that location are v kingdoms; monera, protista, fungi, plantae and animalia. On the other hand, all living organisms belong to three domains namely, bacteria, archaea and eukarya. Similarly, domain Eukarya includes protista, fungi, plantae and animalia. Hence, this is the difference betwixt kingdom and domain.
