What is the primary characteristic on which the first division of organisms is made?
The primary characteristic on which the first division of organisms is made is the nature / kind of the cell - prokaryotic and eukaryotic cells. Nature of the cell includes the presence or absence of membrane-bound organelles. Therefore, on the basis of this fundamental characteristic, we can classify all living organisms into two broad categories of eukaryotes (protista, fungi, plantae, animalia) and prokaryotes (monera). Then, further classification is made on the basis of cellularity or modes of nutrition, sexual reproduction and phylogenetic relationship.
