Assertion: Classification is necessary to study all living organisms Reason: In classification, the individuals are grouped into categories (a) Both Assertion and Reason are correct and Reason is the correct explanation for Assertion. (b) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion. (c) Assertion is correct but Reason is incorrect. (d) Both Assertion and Reason are incorrect.
Hint: This is very important because it helps to establish the relationship among various groups of organisms and it also helps to study the phylogeny and evolutionary history of organisms.
Correct answer: Both the Assertion and Reason regarding the topic classification are correct and also Reason is the correct explanation for Assertion. To study all the existing and even extinct living organisms is nearly impossible for us. So it has become very essential to group the individuals into categories on the basis of various characteristics. This is referred to as classification which makes it possible to study all the existing and extinct living organisms by studying the category-wise characteristics.
Additional Information: -Taxonomy is the science of classifying living organisms. -The classification of living things is done in order to organize and make sense of the incredible diversity of life. -The organisms that have similar proteins and DNA are grouped together. -The basis of modern classification was formed by the classification system introduced by Linnaeus. -Binomial nomenclature for naming species was also developed by Linnaeus. -Scientists have added more recently the domain to the Linnaean system of classification. They have recognised three main domains namely Archaea, Bacteria, and Eukarya. -The Archaea Domain includes only those organisms that belong to the Archaea Kingdom whereas the Bacteria Domain includes only those organisms that belong to the Bacteria Kingdom. -The third and last Eukarya Domain includes the organisms belonging to the kingdoms of Animal, Plant, Fungus, and Protist. -Since viruses lack most of the defining traits of living things many scientists think that they should not be classified as living things.
So, the correct answer is, 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Note: The seven divisions of the classification system are Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. The classification system facilitates the identification of organisms. To learn about different kinds of plants and animals, their features, similarities and differences, this is possible only with the help of classification.
