Furthermore that the lightest and most polar pigments would travel the most while the most non-polar and heaviest would be left in the bottom of the paper.

The second experiment in our lab consisted on observing electron transport in chloroplasts. This was done using an electron acceptor called DCPIP which is a dye is blue in its oxidized state is blue but after accepting electrons becomes colorless. Therefore we could determine if electron transfer had occurred depending on the change in the solutions color. My hypothesis for this was that all the test tubes containing DCPIP would become clear, including test tube four which was placed in the dark since it has been proven that electron ...
