Paper 1

1. D2. A3. B4. C5. A6. A7. C

Paper 2

1. a) The seeds absorbed water, swelled and caused the testes to split

b) i) To prevent oxygen in the air from dissolving in the water

ii) Boiled water will contain no dissolved oxygen.

c) Place the seeds in location with air, water and warmth.

d) Germination of seeds require water, air and suitable temperature only. No sunlight

needed

e)The damp newspaper provided water for germination

f) 1. Store in dry places

2. Store in a cold place like refrigerator

3. Store in an air tight container

2. a) i)

ii) The shoot of the plants grow towards the sunlight.

iii) Phototropism

iv) Phototropism is important for the process of photosynthesis which needs sunlight to produce food.

b) i) Roots Q and R grow towards direction of water, which shows positive hydrotropism.

ii) Because there is no water in beaker S which makes the roots attracted to gravity or positive geotropism.
