    3. Who is known as the 'Father of Taxonomy'?

      • (a) Aristotle
      • (b) Linnaeus
      • (c) Darwin
      • (d) Mendel

      Explanation: Linnaeus is considered the Father of Taxonomy due to his system of binomial nomenclature.

    4. Binomial nomenclature means:

      • (a) One name given to a species
      • (b) Two names given to a species
      • (c) Three names given to a species
      • (d) Many names given to a species

      Explanation: Two names given to a species, the genus and the specific epithet.

    5. Which of the following is the correct sequence of taxonomic categories?

      • (a) Kingdom, Phylum, Class, Order, Family, Genus, Species
      • (b) Kingdom, Class, Phylum, Order, Family, Genus, Species
      • (c) Kingdom, Phylum, Class, Family, Order, Genus, Species
      • (d) Kingdom, Phylum, Order, Class, Family, Genus, Species

      Explanation: Kingdom, Phylum, Class, Order, Family, Genus, Species is the correct hierarchical sequence.

    MCQ Set 3: Taxonomic Aids

    Taxonomic aids are super useful tools that help us identify and classify organisms. Think of them as reference libraries and field guides for biologists. These MCQs will test your knowledge of herbaria, botanical gardens, zoological parks, and museums.
