Detailed explanation-1: -Emerson & Arnold were the two scientists who worked on Chlorella and gave the two pigment system theory or two photosystems theory.
Detailed explanation-2: -The light excites the chlorophyll molecules at the reaction centre and causes an increase in energy.
Detailed explanation-3: -Each pigment system (or photo-system) consists of a central core complex (CC) and a light harvesting complex (LHC). In pigment system I and II, these are called as CCI, LHCI and CCII, LHCII respectively. The light harvesting complexes contain antenna pigments associated with proteins.
Detailed explanation-4: -The major groups of photosynthetic pigments are: Chlorophyll. Carotenoids. Phycobilins.
Detailed explanation-5: -Louis Duysens first proposed the concepts of Photosystems I and II in 1960, and, in the same year, a proposal by Fay Bendall and Robert Hill assembled earlier discoveries into a coherent theory of serial photosynthetic reactions.
