2. Why is hot methanol used to drop samples of photosynthesising algae into in the Calvin lollipop experiment?
- Because it instantly stops the reaction by boiling the water present in the algae
- Because it instantly stops the reaction by denaturing enzymes for photosyntheis
- because it allows substances into which C14 is incorporated to be identified
- Because it is a limiting factor to photosynthesis
3. In the light-indepedent reaction (Calvin cycle) Ribulose biphospate combines with CO2, aided by enzyme action. What is the product of this?
- ADP and Pi
- Glycerate 3 phospate
- Triose phospate

4. Where does the light-dependent reaction take place?
- In the lower mesophyll layer only
- In the thylakoid membrane of the chloroplast
- In the stroma
- In the chloroplast membrane
5. It is called the 'compensation point' when...
- CO2 concentration (released) = O2 concentration (absorbed)
- Light absorbed = respiration rate
- Respiration rate = Photosynthesis rate
