✅ Multiple Choice Questions (MCQs)
1. The movement of particles from high to low concentration without energy is called:
A. Osmosis
B. Active transport
C. Diffusion
D. Filtration
✅ Answer: C

2. Osmosis involves the movement of:
A. Salt only
B. Glucose
C. Water
D. Protein
✅ Answer: C

3. Which of the following requires energy?
A. Osmosis
B. Active Transport
C. Diffusion
D. Respiration
✅ Answer: B

4. A plant cell placed in a strong salt solution will:
A. Remain unchanged
B. Burst
C. Shrink
D. Grow larger
✅ Answer: C

5. Active transport is important in:
A. Swelling of red blood cells
B. Movement of oxygen in lungs
C. Uptake of minerals by roots
D. Diffusion of urea in kidneys
✅ Answer: C

✅ Theory Questions
6. Define diffusion and give one biological example.
✅ Answer: Diffusion is the movement of particles from high to low concentration. Example: Oxygen diffusing into blood.

7. What is osmosis? Use a diagram to illustrate your answer.
✅ Answer: Osmosis is the movement of water through a semi-permeable membrane. (Include simple diagram).

8. Give two differences between osmosis and active transport.
✅ Answer:

Osmosis does not need energy; active transport does.

Osmosis moves water; active transport moves solutes.

9. State two importance of active transport in living organisms.
✅ Answer:

Absorption of minerals by roots

Reabsorption of glucose in kidneys

10. Design an experiment to show that osmosis occurs.
✅ Answer: Use dialysis tubing filled with sugar solution in water, observe swelling.
