Cambridge IGCSE Biology 0610 Paper 2 Multiple Choice Extended (Sample) 2023
Paper 2 of IGCSE Biology is where the exam tests whether you can actually think like a biologist — not just recall facts, but apply them to unfamiliar scenarios and spot the biological principle buried in a real-world situation. This sample paper mirrors the extended version's mix: it covers cells and organisation, biochemistry and nutrition, plus transport and gas exchange, using the multiple-choice format that rewards careful reasoning and eliminates careless mistakes. You'll encounter questions that look simple but hide classic misconceptions, diagrams that demand close reading, and calculations that test whether you understand the concept, not just the formula. By the time you finish, you'll know whether you can confidently distinguish between prokaryotic and eukaryotic structures, predict how enzymes behave under different conditions, explain why plant cells need a cuticle on their leaves, and apply the theory of gas exchange to unfamiliar tissues — exactly the skills Paper 2 assesses.

Answers hidden — play to find out.
- Question 1
Which statement correctly describes a difference between prokaryotic and eukaryotic cells?
- Question 2
Which of the following is the correct function of rough endoplasmic reticulum (rough ER)?
- Question 3
In a plant cell, the cell wall provides structural support, but it is the _____ that controls the movement of substances in and out of the cell.
- Question 4
What happens to the rate of an enzyme-controlled reaction if the temperature is increased from 35 °C to 50 °C, assuming the enzyme has not denatured?
- Question 5
During photosynthesis, chlorophyll absorbs light energy primarily to drive which process?
- Question 6
True or False: In the light-independent reactions of photosynthesis, carbon dioxide is fixed by combining with a 6-carbon sugar called glucose.
- Question 7
Which feature of a leaf is primarily adapted to reduce water loss by evaporation?
- Question 8
In animal cells, glucose is transported across the cell membrane against its concentration gradient. Which term best describes this process?
- Question 9
Water molecules move from a dilute solution (low solute concentration) to a concentrated solution (high solute concentration) across a partially permeable membrane. What is the name of this process?
- Question 10
Which tissue in plants is primarily responsible for the transport of sugars from leaves to other parts of the plant?
- Question 11
The human gas exchange system allows oxygen to enter the blood and carbon dioxide to leave. Which feature of the alveoli makes them well-adapted for rapid gas exchange?
- Question 12
True or False: In a fish, gas exchange occurs directly across the skin (body surface) and does not involve specialised respiratory structures.
- Question 13
A plant is kept in a dark cupboard for several days. The concentration of which substance in its cells would you expect to decrease?
- Question 14
In a capillary tube, water rises up against gravity. This phenomenon is called capillarity and is partly due to adhesion between water and the capillary walls. Which force primarily opposes this upward movement?
