  • Question 2
    1 / -0
    Which of the following has a real existence?
    Solution
    • Phylum, Class, and Genus are various taxonomical categories that only have a theoretical existence for the sake of convenience while species have a real existence which is defined as a group of interbreeding population. 
    • Example: Cats represent a species having real existence which belong to the genus Felis and family Felidae which do not an organism in living world.
    So, the correct option is 'Species'.
  • Question 3
    1 / -0
    The largest herbarium of the world is located in
    Solution
    • Largest herbarium of the world is situated in Royal Botanical Garden. It's a  326-acre site at Kew with 40 historically important buildings; it became a UNESCO World Heritage Site on 3 July 2003.
    • The collections at Kew and Wakehurst Place include over 28,000 taxa of living plants, 8.3 million plant and fungal herbarium specimens, and 30,000 species in the seed bank.
    So, the correct option is 'Royal Botanical Garden, Kew'.
  • Question 4
    1 / -0
    A non-obligate component of hierarchy of categories used by Linnaeus was
    Solution
    • The 7 obligate taxonomic hierarchy used by Carolus Linnaeus in the descending order is Kingdom → Phylum → Class → Order → Family → Genus → Species.
    • Since variety doesn't fall in the above category, it is a non-obligate component.
    So, the correct option is 'Variety'.
  • Question 5

    Basic unit or smallest taxon of taxonomy/classification is 
    Solution
    • The correct taxonomic hierarchy in the correct order is given by
    Kingdom → Phylum → Class → Order → Family → Genus → Species
    • Species is the lowest level of classification and shows the high level of similarities among the organisms. One species can be distinguished from other closely related species based on distinct differences in morphology.
    So, the correct option is 'Species'.
  • Question 8
    1 / -0
    A non-obligate category introduced between class and division is 
    Solution
    Between the Class and Division category, superclass is introduced which refers to the assemblage of similar classes.

    A. Tribe is introduced between Family and Genus and it refers to a group of genera.
    B. Subclass is introduced between Class and Order.
    C. Superclass is introduced between Division (or phylum) and Class.
    D. Taxon is any group in the whole hierarchy of classification.
    Hence, the correct answer is 'Superclass'
  • Question 9
    1 / -0
    Correlated characters are similar traits found in
    Solution
