Lab 4B Color Chart Analysis: 1. What factors are involved in the separation of the pigments? The solubility, size of particles, and their attractiveness to the paper are all involved in the separation. 2. Would you expect the Rf value of the pigment to be the same if a different solvent were used? Explain. No, the different solubilities of the pigments would change the Rf values. For example chlorophyll b is only soluble to fat solutions. 3. What type of chlorophyll does the reaction center contain? What are the roles of the other pig- ments?

The reaction center contains chlorophyll a. The other pigments collect different light waves and transfer the energy to chlorophyll a. 4. What is the purpose of DPIP in this experiment? DPIP is the electron acceptor in this experiment. 5. What molecule found in chloroplasts does DPIP "replace" in this experiment? DPIP substitutes for the NADP molecules. 6. What is the source of the electrons that will reduce DPIP?
