SA2 Practice Paper — Version 2: Answer Key

Total Marks: 60

Section A (10 marks)

1. B — By whether they have backbones. (1 mark) Teaching note: Diversity means variety. Scientists group living things by real biological features such as presence of backbone, not by human objects.

2. C — Fish. (1 mark) Fish have backbones, so they are vertebrates. Insects, worms, jellyfish do not.

3. A — Mango tree reproduces from seeds, fern from spores. (1 mark) Flowering plants (mango) use seeds; non-flowering plants (fern) use spores.

4. C — Type of phone used. (1 mark) Phone is not a biological feature; others are valid diversity traits.

5. B — do not make their own food using sunlight. (1 mark) Fungi absorb food; plants make food by photosynthesis.

6. B — Bacteria. (1 mark) Bacteria are tiny living things seen only under microscope = microorganisms.

7. B — backbones. (1 mark) Vertebrates/invertebrates split is by backbone.

8. B — Fern and moss. (1 mark) Both are non-flowering; others are flowering.

9. B — different living things play different roles to keep nature balanced. (1 mark)

10. B — Classification helps us organise living things by their features. (1 mark)

Section B (12 marks)

11. (2 marks: 1 for each group + example) Vertebrates — e.g. cat; Invertebrates — e.g. insect. Teaching: Backbone presence is a main diversity divider.

12. (2 marks) Flowering plants produce flowers and seeds; non-flowering do not produce flowers (e.g. use spores). (1 for each side)

13. (2 marks) Any two: body covering (feathers, scales), number of legs, presence of backbone, how they reproduce. (1 each)

14. (2 marks) Bacteria are too small to be seen with eyes alone (1) and are living things studied as microorganisms (1).

15. (2 marks) Example: mushroom (1). Different: does not make food using sunlight / not green (1).

16. (2 marks) To organise them by features (1) and study similarities/differences (1).

Section C (38 marks)

17. (3 marks) (a) W and Z (fish, cat) (1) (b) Y (fern) (1) (c) X (mushroom) (1) Image note: W/Z drawn with backbone hint, X cap-stem fungus, Y leafy non-flower.

18. (4 marks) (a) Animals: lizard; Plants: rose bush, mushroom, fern (2: 1 for animal, 1 for plant list) (b) Flowering: rose bush; Non-flowering: mushroom (fungus), fern (2: 1 each) Teaching: Mushroom is fungus, not plant, but commonly grouped separately from flowering plants in P5 diversity.

19. (4 marks) Vertebrates — e.g. cat — has backbone Invertebrates — e.g. worm — no backbone Flowering plants — e.g. rose — produces flowers/seeds Non-flowering plants — e.g. fern — no flowers/spores (1 mark per cell correctly filled)

20. (4 marks) (a) Animals: butterfly, dog (1). Because they are living things that move and do not make their own food (1). (b) Plants: tomato plant (1). Microorganism: bacteria (1). Teaching: Diversity classification uses size, structure, reproduction.
