  1. What was the name of the green pigment that you separated in this experiment?  Why is it important to photosynthesis?

    The green pigment is chlorophyll.  It is essential to photosynthesis because it traps the energy from the sun that drives the photosynthesis reaction.

  2. Your experiment may have produced various colours.  Where did these colours come from, and what is their purpose?

    The other colours are also leaf pigments.  These pigments have the same role as chlorophyll, which is helping to capture the sun's energy for photosynthesis.
