Section B (Questions 11–16, 2 marks each)

State two ways in which plants can be grouped by their diversity.

Explain one difference between a flowering plant and a fern.

List two characteristics of mammals.

Describe how animals can be grouped as vertebrates and invertebrates. Give one example of each.

State two reasons why biodiversity is important.

A seed has a hook that sticks to animal fur. Which method of dispersal is this, and why is it useful?

Section C (Questions 17–20, 3 marks each)

The diagram below shows four living things.

Image pending generation: diagram for Q17.

Group them into plants and animals. Then state one feature of the plants group. (3 marks)

Explain how diversity helps living things survive when the environment changes. Use an example in your answer. (3 marks)

Compare the reproduction of a flowering plant and a fern. State one similarity and one difference. (3 marks)

A student found three leaves: Leaf X has narrow shape, Leaf Y is broad, Leaf Z is needle-like. Explain how leaf shape shows diversity and how it may help the plant. (3 marks)

Primary 5 Science Quiz - Diversity (Answer Key)

Total Marks: 40
Topic: Diversity
Caveat: No past-year paper evidence exists for P5 Science; this quiz is syllabus-first using LLM-inferred patterns from Stage 4. It is not exam-derived.

Section A Answers (1 mark each)

C (Body structure and features)
Teaching note: Diversity means differences among living things. Scientists group them by observable body features, not by human objects.
C (Fish)
Teaching note: Fish typically have scales and use gills to breathe underwater.
B (Fungus)
Teaching note: Mushrooms are fungi, a separate group from plants and animals.
D (By electricity)
Teaching note: Seeds disperse by wind, water, animals, or explosion — not electricity.
B (Ferns)
Teaching note: Ferns reproduce via spores, not seeds.
C (Frog)
Teaching note: Vertebrates have backbones; frog is an amphibian with backbone.
B (Survive in different environments)
Teaching note: Diversity allows species to occupy different habitats.
B (Have 3 body parts and 6 legs)
Teaching note: Insects have head, thorax, abdomen and 6 legs.
C (Birds)
Teaching note: Birds lay eggs and have feathers.
A (To make them easier to study and understand)
Teaching note: Classification helps scientists organise knowledge.

Section B Answers (2 marks each)

Two ways: (1) By whether they are plants or animals; (2) By reproduction method (seeds vs spores) OR by presence of backbone.
Marking: 1 mark per correct way.
Teaching note: Grouping helps show diversity.
Difference: Flowering plants produce flowers and seeds; ferns do not have flowers and reproduce by spores.
Marking: 2 marks for clear difference.
Teaching note: This shows plant diversity.
Two characteristics: (1) Have hair/fur; (2) Feed young with milk.
Marking: 1 mark each.
Teaching note: These define mammals.
Vertebrates have backbone (e.g., frog); invertebrates have no backbone (e.g., spider).
Marking: 1 mark definition, 1 mark examples.
Teaching note: This is a main animal diversity split.
Two reasons: (1) Keeps ecosystems balanced; (2) Provides food and resources for humans.
Marking: 1 mark each.
Teaching note: Biodiversity supports life.
Method: Dispersal by animals. Useful because hooks attach to fur and drop elsewhere, reducing competition.
Marking: 1 mark method, 1 mark reason.

Section C Answers (3 marks each)

Plants: A (Rose), B (Fern). Animals: C (Fish), D (Bird). Feature: Plants make their own food / do not move about.
Marking: 1 mark plants group, 1 mark animals group, 1 mark feature.
Image note: Diagram shows rose & fern as plants; fish & bird as animals.
Explanation: Diversity means different traits exist. If environment changes (e.g., drier climate), some variants survive. Example: plants with deep roots survive drought.
Marking: 1 mark diversity, 1 mark example, 1 mark link.
Similarity: Both reproduce to make new plants. Difference: Flowering plant uses seeds; fern uses spores.
Marking: 1 mark similarity, 2 marks difference (or 1+1).
Explanation: Leaf shape varies (diversity). Narrow/needle leaves reduce water loss in dry/cold places; broad leaves catch more light in wet areas.
Marking: 1 mark diversity stated, 2 marks link to function.
