I completed a StudyVector GCSE Biology derived predicted-practice paper (2026) and scored 0/36. This is practice-only and not an official paper:

Section A

Answer all questions.

Question A1 (1 mark)
Which organelle is the site of photosynthesis?
A. MitochondrionB. RibosomeC. ChloroplastD. Nucleus
Question A2 (3 marks)
Explain one way the structure of a root hair cell is adapted for absorption of water and mineral ions.
Question A3 (4 marks)
Describe the difference between a bacterial cell and a plant cell. Give two structural differences.
Question A4 (1 mark)
Which blood vessel carries blood towards the heart?
A. ArteryB. VeinC. CapillaryD. Vena cava only

Section B

Answer both questions.

Question B1 (6 marks)
A student investigates the effect of light intensity on the rate of photosynthesis using pondweed. Describe two control variables they should keep constant and explain why each matters.
Question B2 (6 marks)
In a food chain: grass → rabbit → fox. Explain why there are fewer foxes than rabbits, using the idea of energy transfer.

Section C

Answer the question.

Question C1 (5 marks)
Vaccination helps protect against infectious disease. Describe how vaccination leads to immunity.
Question C2 (5 marks)
Suggest one ethical issue with using animals in drug testing and one way scientists try to reduce harm.
Question C3 (5 marks)
Explain why quadrats are used when estimating population size of plants in a field.
