1. Why is the rate of photosynthesis not equal to the net uptake of CO2 by a plant?

  • Because venus flytraps are carnivores
  • Because some CO2 produced in respiration is used for photosynthesis
  • Because CO2 is used only in the light-indepedent reaction
  • Because the rate of photosynthesis increases with temperature

2. How good was this quiz?

  • simply fabulous
  • wait, is that a squirrel?
  • meh
  • it was very good, thank you for asking

3. Where does the light-dependent reaction take place?

  • In the stroma
  • In the thylakoid membrane of the chloroplast
  • In the chloroplast membrane
  • In the lower mesophyll layer only

4. 'The rate of photosynthesis is affected by the factor whose level is at the least favourable value' this is called the...

  • stopping factor
  • least favourable factor
  • limiting factor
  • limited factor

5. Why is hot methanol used to drop samples of photosynthesising algae into in the Calvin lollipop experiment?

  • 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 instantly stops the reaction by boiling the water present in the algae
  • Because it is a limiting factor to photosynthesis
