Classification Of Animal Kingdoms
Eukaryotic organisms can be unicellular or pluricellular beings formed by many cells its main characteristic is that its genetic.
Classification of animal kingdoms. The first and most basic characteristic for the classification of the animal kingdom is the level of organisation of the cells that are present in the body of an organism. This system of animal kingdom classification was developed by swedish botanist carolus carl linnaeus in the 1700 s. Animals are multicellular eukaryotes. Prokaryotic organisms unicellular eukaryotes and multicellular eukaryotes.
It is further divided into different phyla. Each phylum has organisms that have common characteristics. Apart from the primary distinguishing features of the animal kingdom eukaryotic multicellular without a cell wall and heterotrophic. Prokaryotes are unicellular organisms which means they are formed by a single cell and are characterized by no nucleus in their interior.
Classification of animals is termed as kingdom animalia. Basis of classification the animal kingdom is the largest kingdom amongst the five kingdoms consisting of all animals. In the classification of animals chart they move from the simplest to the most complex. Based on the linnaeus method species are arranged grouped based on shared characteristics.
For example sponges have loosely arranged cell aggregates i e they lack the cellular level of organisation. These are nothing but divisions in which animals organisms with the same characteristics are included under them. It is of three types i. Their genetic material floats inside the cell.
There is a. They are all equally crucial under this kingdom. Animal kingdom classification is an important system for understanding how all living organisms are related. This kingdom includes eleven main phylum divisions porifera coelenterata ctenophora platyhelminthes aschelminthes annelida arthropoda mollusca echinodermata hemichordata and chordata.
Animals are multicellular yet there is a difference in the pattern of organisation of cells. Basis for classification of animal kingdom.
