1. Why are there different pigments present in the chloroplast?
- Because each pigment is a different colour
- Because each pigment is located in a different part of the chloroplast and are thus in different conditions
- Because each pigment absorbs different wavelengths of light
- Because some pigments absorb infrared radiation

3. Why is hot methanol used to drop samples of photosynthesising algae into in the Calvin lollipop experiment?
- Because it is a limiting factor to photosynthesis
- Because it instantly stops the reaction by denaturing enzymes for photosyntheis
