Primary 6 Science - Diversity of Living and Non-Living Things
Quiz 01 | Answer Key
Section A: Multiple Choice Questions (2 marks each)
1. C) They can move from place to place
Not all living things can move from place to place (e.g., plants)
2. B) Snake, fish, frog
These all have backbones (vertebrates)
3. C) They feed on dead or living matter
Fungi cannot make their own food and do not have chlorophyll
4. C) Hibiscus
Hibiscus produces flowers and seeds; ferns and mosses are non-flowering plants; pine trees are conifers (non-flowering)
5. B) Has scales and lays eggs on land
Characteristics of reptiles include scales, laying eggs on land, and breathing through lungs
Section B: Classification Questions (3 marks each)
6.
| Organism | Group |
|---|---|
| Penguin | Bird |
| Dolphin | Mammal |
| Crocodile | Reptile |
| Salamander | Amphibian |
| Shark | Fish |
(0.5 marks each, total 2.5 marks, rounded to 3)
7. Three characteristics of insects (any three):
- They have 6 legs
- They have 3 body parts (head, thorax, abdomen)
- They have a pair of antennae
- They have an exoskeleton
- Most have wings (1 or 2 pairs)
(1 mark each)
8.
| Characteristic | Plants | Animals |
|---|---|---|
| Make their own food | Yes | No |
| Can move from place to place | No | Yes |
| Have cell walls | Yes | No |
(0.5 marks each cell, total 3 marks)
Section C: Short Answer Questions (4 marks each)
9. (a) Arachnid (2 marks) (b) Spider / Scorpion / Tick (2 marks)
10. A whale is classified as a mammal because:
- It breathes air using lungs (not gills) (2 marks)
- It gives birth to live young and produces milk to feed its young (2 marks)
- It is warm-blooded (1 mark - bonus if mentioned)
- It has hair/fur (even if only a little) (1 mark - bonus if mentioned)
11. (a) Grass (the producer that makes its own food) (2 marks) (b) The frog population would decrease because:
- Snakes are predators of frogs
- More snakes would eat more frogs
- Therefore, fewer frogs would survive (2 marks for explanation)
Section D: Structured Questions (5 marks each)
12. (a) Fern and Moss (1 mark)
(b) Mushroom is not a plant. It belongs to the Fungi kingdom. (2 marks)
(c) Flowering plants reproduce through seeds that develop from flowers, while non-flowering plants like ferns reproduce through spores, and mosses also reproduce through spores. Non-flowering plants do not produce flowers or seeds. (2 marks)
13. (a) Classifications:
- Turtle: Reptile
- Toad: Amphibian
- Goldfish: Fish (2 marks for all correct)
(b) Amphibians' eggs do not have hard shells and need to be kept moist to prevent drying out. The eggs would dry out on land. (1 mark)
(c) Fish breathe through gills, which extract oxygen from water. On land, their gills cannot extract oxygen from the air efficiently, and the gills would dry out, causing the fish to suffocate and die. (2 marks)
Section E: Higher-Order Thinking (5 marks)
14. (a) Bird (specifically, it describes a penguin) (1 mark)
(b) Possible adaptations (any two):
- Thick layer of fat/blubber under the skin for insulation
- Thick, waterproof feathers to keep warm and dry
- Huddling together in groups to conserve heat
- Dark coloured feathers to absorb heat from the sun
- Ability to slow down metabolism in extreme cold (1 mark each, total 2 marks)
(c) Possible advantages of not flying:
- Heavier body helps them dive deep into the water to catch fish
- Wings adapted as flippers for efficient swimming
- More energy can be used for swimming and keeping warm instead of flying
- Do not need to escape predators by flying as there are few land predators in their habitat (2 marks for reasonable answer with explanation)
