Primary 6 PSLE Science Quiz - Diversity (Answer Key)

Total Marks: 40
Topic: Diversity

Section A Answers (1 mark each)

1. B
   Teaching note: Diversity means differences among living things. A real scientific way to group them is by body structure such as having a backbone (vertebrate) or not (invertebrate). Options A and C are not biological traits.

2. B (invertebrates)
   Teaching note: Animals without backbones are invertebrates. Vertebrates have backbones; mammals are a subgroup of vertebrates; producers are plants.

3. B (Fish, frog, bird)
   Teaching note: Fish, amphibians (frog), and birds are all vertebrates. The other options list only invertebrates.

4. B (Fern)
   Teaching note: Ferns are non-flowering plants that reproduce using spores. Rose, mango, grass use seeds.

5. B
   Teaching note: Fungi lack chlorophyll and cannot photosynthesise; they absorb food. They have no roots/stems/leaves like typical plants.

6. C
   Teaching note: Shoe brand is not a biological characteristic. Real traits: body covering, reproduction, wings.

7. B
   Teaching note: Bacteria are microscopic living things, not plants or animals, and lack backbones.

8. C (Dolphin)
   Teaching note: Dolphins are mammals (breathe air, have hair, give milk). Shark = fish, penguin = bird, lizard = reptile.

9. B
   Teaching note: Diversity = many different kinds with different features.

10. B (A mangrove swamp)
    Teaching note: Different habitat → different community. Pond and tank/pond/garden similar support overlapping groups.

Section B Answers (2 marks each)

11. Vertebrates have backbones; invertebrates do not. [2]
    Marking: 1 mark for each correct contrast side. Common mistake: saying “vertebrates are bigger” (not always true).

12. Any two of: fungi, bacteria. [1+1]
    Teaching note: These are neither animals nor plants.

13. Habitat: pond / garden / mangrove / seashore [1]; Organism: fish / bee / crab / seaweed [1]
    Marking: Must match logically (e.g., pond → fish).

14. Fungi cannot make their own food (no chlorophyll) and absorb nutrients; plants make food by photosynthesis. [2]
    Teaching note: This is the key split from plants.

15. Any two: presence of backbone, body covering, reproduction method, habitat, wings. [1+1]

16. To understand relationships, protect species, and learn how they survive in different habitats. [2]
    Accept: helps classification, conservation, science study.

Section C Answers

17. (a) Diversity means there are many different types of living things with different characteristics. [1]
    (b) Example: some plants reproduce by seeds, others by spores (or flowering vs non-flowering). [1]

18. (a) Insect / worm / spider / crab / jellyfish (any one). [1]
    (b) Group: fish / bird / mammal / reptile / amphibian [1]; Example: salmon / sparrow / cat / snake / frog [1].
    Marking: Both must be correct pair.

19. (a) Has backbone branch (vertebrate). [1]
    From image: Frog is a vertebrate.
    (b) Insect and worm. [1]
    From image: Right branch “No backbone” shows these two.

20. (a) Bacteria are tiny / not animals / no backbone / different cell structure. [1]
    (b) They are living things that grow and reproduce. [1]
