When photosynthetic pigments are extracted from the chloroplasts of green plants, they have a higher tendency to
fluoresce than pigments within intact chloroplasts. Explain this phenomenon. What will be an ideal response?
Concepts to Consider: Extracted pigments are removed from the thylakoid membranes
where other components of the electron transport chain are located. This causes the
uncoupling of the pigment molecules from electron acceptors, which results in a greater
likelihood of fluorescence than in coupled pigment-acceptor systems.
