What is the basis of classification of living organisms?

basis of classification are:

1. type of cell ( eukaryotic or prokaryotic)

2. number of cells present (multicellular or unicellular)

3. whether cell wall is present or not

4. mode of nutrition (autotrophic or heterotrophic or saprophytic)

Classification of Living Things

Scientists have found and described approximately 1.75 million species on Earth. Plus, new species are being discovered every day. From tiny bacteria to yeasts to starfish to blue whales, life's diversity is truly impressive! With such a diversity of life on Earth, how does one go about making sense of it all?

One way to make sense of it is by classification. Scientists put similar species into groups so that those millions of species do not seem so overwhelming. People rely on their knowledge of classification to understand what different species are like. You may have done this without even thinking about it! For instance, let’s say that a friend of yours tells you that he saw an egret last weekend. You have never heard of an egret before, but if he tells you that an egret is a type of bird, you should have some idea of what it is like.

Living things are divided into three groups based on their genetic similarity. The three groups are:

These three groups are called domains. The figure at the left shows the three domains of life. The distance between groups indicates how closely related they are. Groups that are close together, like plants and animals, are much more closely related than groups that are far apart, like plants and bacteria. Do you see how the two types of microbes, Archaea and Eubacteria, are about as similar to one another as they are to animals? Recent studies have found that microbes are far more diverse than anyone had suspected.

The Eukaryota domain is divided into several groups called kingdoms.

Within each kingdom, species are further classified into groups based on similarities. For example, the full classification of a human is:

Domain Eukarya Kingdom Animalia Phylum Chordata Subphylum Vertebrata Class Mammalia Order Primates Family Hominidae Genus Homo Species sapiens

Biological classification is putting organisms into groups. This is part of Scientific Taxonomy. Classification is the arrangement of different related organism groups put into different groups. The classification system starts with a group with a wide variety of organisms and becoming more selective as the groups get more specific. CarlLinnaeusclassified organism by shared characteristics.CarlLinnaeuswas the first person who started the idea of classifying. He is sometimes called the father of taxonomy. He loved plants and showed an interest in organisms from an early age. Linnaeusdeveloped the system to classify and organize organisms into groups. Along with founding the concept of classification, Carl wrote books on classification of organisms to.

Basis of classification include: 1. Nature of cell: Nature of the cell is considered to be the fundamental feature, as it gives rise to another feature called cellularity. It includes the presence or absence of membrane-bound organelles. Therefore, on the basis of this fundamental characteristic, we can classify living organisms into two broad categories of eukaryotes and prokaryotes. 2. Cellularity: Unicellular organisms are those organisms whose body is made up of a single cell, whereas multicellular organisms are those organisms whose body is made up of many cells. Multicellular organisms use the principle of division of labour to perform specialized functions. This results in a specific body design that distinguishes multicellular organisms from unicellular organisms. 3. Mode of nutrition: The mode of nutrition also distinguishes different organisms. The ability to manufacture their own food makes the body design of plants different from that of animals.
