Biology Year 11 - Module 2 - Lesson 20
Autotrophs vs Heterotrophs — Full Module Synthesis
1. Key Ideas
This lesson pulls together all three inquiry questions into one coherent comparison. If you can explain the differences between a leaf cell and a liver cell across nutrition, gas exchange, and transport — you understand Module 2.
- Synthesise the nutrient and gas requirements of autotrophs vs heterotrophs
- Compare nutrient and gas requirements of autotrophs and heterotrophs (IQ2)
2. Success Criteria
By the end, you should be able to:
- Synthesise the nutrient and gas requirements of autotrophs vs heterotrophs
- Compare gas exchange structures across both kingdoms
- Compare transport systems and composition changes across both kingdoms

5. Short Answer Questions
1. 6. Explain why a plant that is photosynthesising still requires cellular respiration. In your answer, explain what each process produces and why both are necessary simultaneously.
2. 7. Using the data in Table A (Card 5), explain the changes in O₂ and glucose concentration between the pulmonary vein and the vena cava. Refer to specific organs in your answer.
6. Extend: Apply the Idea
A student gives a memorised answer about Autotrophs vs Heterotrophs — Full Module Synthesis but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.

A. Identify the key concept being tested
B. Write every fact from memory
C. Ignore the command word
D. Skip examples and evidence
2. Which answer would show stronger understanding of Autotrophs vs Heterotrophs — Full Module Synthesis?
A. An answer with accurate terms and reasoning
B. A copied definition only
C. A single-word response
D. An answer with no example
3. What should you do if a question asks you to explain?
A. Link the idea to a reason or cause
B. List unrelated facts
