SECTION B – SHORT ANSWERS (2 × 4 = 8 MARKS)
(Attempt all questions)
11. Define taxonomic hierarchy.
Ans:
Taxonomic hierarchy is the systematic arrangement of organisms into successive categories from species to kingdom based on similarities and differences.
12. Why is species considered the basic unit of classification?
Ans:
Species is considered the basic unit because:
Members share maximum similarities
They are morphologically distinct from other species
13. Distinguish between genus and family.
Ans:
|
Genus |
Family |
|
Group of related species |
Group of related genera |
|
Lower category |
Higher category |
14. What is taxonomy? Mention its basic processes.
Ans:
Taxonomy is the branch of biology dealing with identification, classification, nomenclature and characterisation of organisms.
SECTION C – CASE-BASED QUESTION (5 MARKS)
15.
A student studied lion, tiger and leopard and found that they share many common characters but still belong to different species.
(a) Name the genus to which they belong. (1)
Ans: Panthera
(b) Why are they placed under different species? (2)
Ans:
They differ in morphological characters and possess distinct specific epithets.
(c) Name the family to which they belong. (1)
Ans: Felidae
(d) State one reason why classification becomes complex at higher taxonomic levels. (1)
Ans:
Because similarities decrease and diversity increases.
SECTION D – LONG ANSWER (5 MARKS)
(Attempt any ONE)
16. Explain taxonomic hierarchy with suitable examples.
Ans (Key Points for Full Marks):
Definition of taxonomic hierarchy
Explanation of species, genus, family, order, class, phylum/division and kingdom
Examples like Homo sapiens, Panthera, Mammalia, Chordata
Mention that similarities decrease upwards
17. Describe species as a taxonomic category.
Ans (Key Points for Full Marks):
Species is the lowest and basic unit
Members show fundamental similarities
Can be distinguished morphologically
Examples: Mangifera indica, Homo sapiens
