What is the basis of classification of organisms?
a. Structure of cells
b. Structure of organism
c. Mode of nutrition
d. All of the above

Answer Verified Verified
Hint: Living organisms are classified depending on their structure and characteristics. In the eighteenth century, this method was developed by Carl Linnaeus.

Complete answer:
> Option A is incorrect. The structure of a nucleus may or may not be organized within an organism. Organisms on this criterion can be classified into two groups i.e., Eukaryotes and Prokaryotes.

> Option B is incorrect. Organelle, cells, tissues, habitats, habitats, organ systems, species, cultures, societies, environment, and biosphere are the biological stages of the structure of living things organized from the simplest to the most complex.

> Option C is incorrect. Based on the mode of nutrition, it is possible to classify species into two distinct classes, i.e. autotrophs and heterotrophs. An autotroph makes its food, while a heterotroph is dependent on other food species.

> Option D is correct. In classifying prokaryotic and eukaryotic species, the arrangement of the cells and the organelles support. For the classification, the organism's structure involves the existence of tissues, organs, body plans, symmetry, form, etc. The basis for classification may be the nutritional mode such as autotrophic, heterotrophic, saprophytic, etc.

Hence, The correct answer is option (D).

Additional information:
In the 17th century, the Swedish physician and botanist Carolus Linnaeus wrote several books on various plant and animal species. He grouped organisms according to common physical characteristics and established the two-part binomial taxonomy method of categorizing organisms according to genus and species, according to his classification scheme. Such a sort of classification has been successful. His work was later merged with Charles Darwin's work, which formed the basis of modern taxonomy.

Note: Scientists described living things as important for biodiversity, and who is connected to living things. They attached the domain to the classification scheme Linnaean. The empire is a taxon larger than the kingdom itself. Three commonly known domains are found: Archaea, Bacteria, and Eukarya.
