Sample questions on The Living World with answers
8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
Question 1: Characteristics of Living Organisms
Reproduction cannot be an all-inclusive defining characteristic of the living organisms because:
- A reproduction is non-living
- B many organisms, such as the mules, the sterile worker bees, and the infertile human couples, do not reproduce
- C it is not observed
- D all organisms reproduce
Answer: B. many organisms, such as the mules, the sterile worker bees, and the infertile human couples, do not reproduce
Why: Hence it is not universal.
Question 2: Taxonomic Categories and Aids
The taxonomic key is:
- A a map
- B a taxonomic aid used for the identification, based on the contrasting characters in a pair, called the couplet
- C a map of the genome
- D a diagram of the cell
Answer: B. a taxonomic aid used for the identification, based on the contrasting characters in a pair, called the couplet
Why: Each statement is a lead.
Question 3: Taxonomic Hierarchy and Nomenclature
In binomial nomenclature, the scientific name of an organism consists of the:
- A family and order
- B genus and species
- C class and phylum
- D kingdom and genus
Answer: B. genus and species
Why: Binomial nomenclature, formalised by Linnaeus, names each organism with two parts: the genus (capitalised) followed by the species epithet (lowercase), both italicised.
Question 4: Taxonomy and Nomenclature
The scientific name of the potato is:
- A Oryza sativa
- B Mangifera indica
- C Solanum tuberosum
- D Triticum aestivum
Answer: C. Solanum tuberosum
Why: Solanum is the genus.
Question 5: Characteristics of Living Organisms
Growth in living organisms differs from growth in non-living objects because it is:
- A extrinsic, by accumulation of material on the surface
- B limited to plants only
- C unrelated to metabolism
- D intrinsic, taking place from within the organism
Answer: D. intrinsic, taking place from within the organism
Why: A mountain or a crystal grows by adding material from outside, while living things grow by dividing and enlarging cells.
Question 6: Taxonomic Categories and Aids
The taxonomic category 'species' is defined as:
- A the largest category
- B a group of individuals with fundamental similarities, which can interbreed
- C a group of families
- D a group of genera
Answer: B. a group of individuals with fundamental similarities, which can interbreed
Why: The species is the lowest category.
Question 7: Taxonomy and Nomenclature
The International Code of Zoological Nomenclature (ICZN) governs the naming of:
- A viruses
- B plants
- C bacteria
- D animals
Answer: D. animals
Why: Plants are named under a separate code.
Question 8: Characteristics of Living Organisms
Consciousness — awareness of and the ability to sense one's environment — is considered by many biologists to be:
- A irrelevant to defining life
- B a defining and easily testable feature of all living organisms
- C a characteristic feature of living organisms, though difficult to define and test precisely
- D exclusive to humans only
Answer: C. a characteristic feature of living organisms, though difficult to define and test precisely
Why: Consciousness is widely regarded as a hallmark of living organisms, though — unlike metabolism — it remains a subjective, difficult-to-define and test characteristic.
