1. Why are there different pigments present in the chloroplast?

  • Because each pigment absorbs different wavelengths of light
  • Because each pigment is located in a different part of the chloroplast and are thus in different conditions
  • Because some pigments absorb infrared radiation
  • Because each pigment is a different colour

Other questions in this quiz

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

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

3. What two products from the light-dependent reaction are used in the light-indepedent reaction?

  • ATP and NADPH
  • NADPH and H2O
  • O2 and ATP
  • O2 and NADPH

4. 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 is a limiting factor to photosynthesis
  • 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

5. The products of the photolysis (splitting) of water are...

  • O2, H+ and a neutron
  • O2, H+ and an electron
  • OH-, H+
  • H+ and an electron
