Answer Key – SA2 Practice Paper (Version 1 of 5) Science Primary 5

Total Marks: 60
Topic: Diversity

Section A (10 marks)

B (1 mark)
Teaching note: Diversity means differences among living things. Grouping by plants vs animals is a basic scientific grouping. Colour of bag or home food is not biological.
B (1 mark)
Fish use gills to take in oxygen from water; birds, mammals use lungs, insects use tracheae.
C (1 mark)
Pot colour is not a property of the plant; it is external.
B (1 mark)
Fungi lack chlorophyll, cannot photosynthesise, unlike plants.
C (1 mark)
Frog is an amphibian with backbone; others are invertebrates.
B (1 mark)
Bacteria are single-celled microorganisms.
B (1 mark)
Diversity includes different reproductive methods (live birth vs eggs).
C (1 mark)
Some bacteria survive extreme habitats like hot springs.
B (1 mark)
Diversity = many kinds with different features.
A (1 mark)
Living groups: Plants, Animals, Fungi, Bacteria. Others are non-living.

Section B (12 marks)

(2 marks)

Body covering (e.g., feathers, scales, skin) – 1 mark
Presence of backbone / how they reproduce / where they live – 1 mark
Teaching: Any two valid characteristics (e.g., habitat, diet, body structure).

(2 marks)
They have different body structures and features: birds have feathers and wings, fish have gills and fins, insects have exoskeletons and antennae. (2 marks for clear difference)
Common mistake: saying they are same because all animals.
(2 marks)
Plants make food using sunlight (chlorophyll); fungi cannot make their own food. (1 difference = 2 marks)
(2 marks)
Example: bacterium in soil / yoghurt; mould on bread; yeast in dough. (name 1 mark, where 1 mark)
(2 marks)
To understand relationships, protect ecosystems, learn medicines/food sources. (any 2 points = 2 marks)
(2 marks)
Vertebrate: bird, fish, frog, sparrow etc. (1 mark)
Invertebrate: insect, worm, snail, ant. (1 mark)

Section C (28 marks)

(a) 3 marks: Plants, Animals, Fungi, Bacteria (any 3 groups, 1 mark each)
(b) 3 marks: e.g., Rose (plant), Cat (animal), Mushroom (fungi) – 1 mark per correct example.
(a) 2 marks: Rose plant and mushroom? No – only rose plant is plant; mushroom is fungi. Accept "rose plant" only if strictly plant-like; but diagram shows mushroom as fungi. Correct: rose plant (1), no second plant. If student says rose plant and mushroom (misclassified) partial? Key: rose plant (1 mark), mushroom is fungi not plant (0). So 1 mark max? To avoid confusion: question asks "plants or plant-like" – mushroom is not plant-like in syllabus; answer: rose plant only (2 marks if only rose plant listed, or 1+1 if two plants shown none). We state: rose plant (2 marks).
(b) 1 mark: Bacterium.
(c) 2 marks: Fish breathes through gills in water; rose plant does not have gills, makes food via sunlight. (1 difference explained = 2 marks)
(a) 4 marks: Animals: ant, snail, sparrow (3). Non-animals: fern (plant), mould (fungi) (2). Total 5 items, 1 mark each correct grouping = 4 marks if all correct? Allocate: 4 marks for 4 correct placements (e.g., ant-animal, fern-non, snail-animal, mould-non, sparrow-animal = 5, but 4 marks means 4 correct). Marking: 1 mark per correct up to 4.
(b) 1 mark: Sparrow (vertebrate bird).
(c) 2 marks: Mould lacks chlorophyll, cannot make food like plants; it is fungus.
(a) 2 marks: Diversity means the variety of different living things with different characteristics.
(b) 4 marks: (1) Each species has role in ecosystem balance; (2) Source of food/medicine; (3) Genetic resource; (4) Beauty/learning. Any 2 well explained = 4 marks (2 marks each).
