Why do We Classify Organisms?

Answer:

Around us, there is a diverse spectrum of life forms (about 10 million to 13 million species). These living forms have been on Earth for millions of years and have diversified. The wide variety of different life forms makes studying them one by one extremely challenging. As a result, we search for commonalities among them and classify them into various classes to examine these various classes as a whole. As a result, classification facilitates our research. 

The type of cells that make up living organisms is a more fundamental criterion for identifying organisms than their surroundings. We can divide all living species into eukaryotes and prokaryotes based on their cell types. On the other hand, a habitat, or the place where an organism lives, is a fairly wide trait that can be used to identify species. Examples are earthworms, mosquitoes, butterflies, rodents, elephants, tigers, and other terrestrial creatures. Except that they share a habitat, these creatures have nothing in common. As a result, the nature or type of a cell is regarded as an essential criterion for classifying living entities.

The constitution of the cell is the basic property on which the first division of organisms is based. It is said to be the most important feature for classifying all living species. The existence or absence of membrane-bound organelles is part of the cell’s nature. As a result, we can divide all living species into two broad categories: eukaryotes and prokaryotes, based on this essential trait. Then, based on cellularity or nutrition modalities, further classification is formed.
