Need for Biological Classification — 30 Q Quiz (30 min)

Need for Biological Classification — 30 Question Quiz

Unit 1: Diversity of Living Organisms • Chapter 1: The Living World — NCERT-based MCQs for CBSE & NEET

Time: 30:00

1. Why is biological classification necessary?

A. To increase the number of species B. To organise and study the diversity of organisms systematically C. To make all organisms identical D. To eliminate rare species

2. Classification helps biologists by:

A. Stopping evolution B. Reducing the number of taxa C. Providing a universal language for naming and identifying organisms D. Only classifying plants

3. One advantage of classification is that it:

A. Helps predict characteristics of organisms based on relatedness B. Prevents species formation C. Eliminates habitat differences D. Stops genetic variation

4. Which of the following is NOT a purpose of classification?

A. To show evolutionary relationships B. To provide identification keys C. To communicate about organisms globally D. To increase the rate of photosynthesis

5. A good classification system groups organisms based on:

A. Natural relationships and common ancestry B. Colour of individuals only C. Names given by local people D. Random selection

6. Which system provides the basic ranks like kingdom, phylum, class?

A. Binomial nomenclature B. Taxonomical hierarchy C. Evolutionary ladder D. Genetic code system

7. Classification helps in conservation because it:

A. Increases hunting B. Hides species locations C. Identifies taxa that are endangered and need protection D. Stops evolution

8. What role do classification keys (like dichotomous keys) play?

A. Measure genetic distance B. Determine age of fossils C. Change species names D. Aid in identification of organisms using successive choices

9. Which scientist is known as the 'father of taxonomy'?

A. Carl Linnaeus B. Charles Darwin C. Gregor Mendel D. Watson & Crick

10. Nomenclature is important because it:

A. Increases the number of names for one species B. Provides unique and universal names for organisms C. Makes naming optional D. Restricts naming to local languages

11. Classification based on evolutionary relationships is called:

A. Artificial classification B. Numerical taxonomy C. Phylogenetic or natural classification D. Phenetics only

12. An identification key commonly uses which type of characters?

A. Molecular characters only B. Behavioural characters only C. Genetic code sequences only D. Observable morphological characters for practical use

13. Artificial classification groups organisms by:

A. A few selected characters like colour or shape B. DNA sequences only C. Geographical boundaries only D. Their economic value only

14. Which practice reduces confusion in scientific names?

A. Using multiple common names B. Using binomial nomenclature C. Avoiding scientific names D. Naming species after towns only

15. Which level of classification is broader than genus but narrower than class?

A. Species B. Order C. Family D. Phylum

16. Numerical taxonomy uses which approach?

A. Quantitative methods and overall similarity measures B. Only fossil records C. Random grouping D. Colour-based sorting only

17. Which is a drawback of common names?

A. They are Latin-based B. They vary regionally and cause confusion C. They are always unique D. They are accepted globally

18. Which tool helps scientists visualise evolutionary relationships?

A. Bar graph only B. Pie chart C. Table of contents D. Phylogenetic tree (cladogram)

19. Which of these is true about scientific names?

A. They are unique and follow binomial format B. They are usually in local dialects C. They change daily D. They are not used in science

20. The scientific name of tiger is Panthera tigris. 'Panthera' represents the:

A. Species name B. Family name C. Genus name D. Order name

21. Which is the correct order of taxonomic ranks from broad to specific?

A. Species, Genus, Family, Order B. Kingdom, Phylum, Class, Order, Family, Genus, Species C. Genus, Species, Family, Order D. Order, Family, Class, Phylum, Kingdom

22. Phenetic classification groups organisms based on:

A. Genetic sequencing only B. Behavioural traits only C. Fossil records only D. Overall similarity of many characters

23. A taxonomist's main job is to:

A. Identify, describe and classify organisms B. Only collect fossils C. Grow crops in the lab D. Work only with microbes

24. Which of these is a limitation of classification?

A. It helps in conservation B. Some organisms show continuous variation making boundaries unclear C. It simplifies study of organisms D. It helps in predicting properties

25. Which naming system uses two names for each species?

A. Polynomial nomenclature B. Trinomial system C. Binomial nomenclature D. Common naming

26. The specific epithet in Homo sapiens refers to which rank?

A. Species B. Genus C. Family D. Order

27. Which code governs the naming of plants?

A. International Code of Zoological Nomenclature B. International Code of Nomenclature for algae, fungi and plants C. ICD code D. WHO naming code

28. Homologous characters used in classification indicate:

A. Same function but different origin B. Unrelated traits C. Only environmental adaptation D. Common ancestry and similar origin

29. Which of the following correctly writes the scientific name of wheat?

A. Triticum aestivum (italicized) B. triticum Aestivum C. Triticum Aestivum (not italicized) D. Triticum_aestivum

30. Why is a universal system of classification useful in science?

A. It allows only one country to name species B. It increases local naming variations C. It ensures consistent communication and avoids ambiguity D. It prevents discovery of new species
