It serves as a component of many vital enzymes such as cytochromes of the electron transport chain, and it is thus required for a wide range of biological functions. All these reactions are very complicated to understand but the main point here is that sunlight has the main role to charge up those dimmers (p680 and p700) exciting another chain reaction which leads to the synthesis of glucose molecule responsible for providing energy to plants.

Effect of Iron Deficiency on Chlorophyll Synthesis 1 2 H. V. Marsh, Jr.3, H. J. Evans4, and G. Matrone North Carolina State College, Raleigh Introduction Since iron deficiency in plants results in severe chlorosis of leaves, it has been assumed by many that iron is an essential cofactor in the biosynthesis of chlorophyll.
