Description 153-158
A model  is
proposed for the organization of chlorophyll-protein complex in photosystem II
(PS II ) of higher plants. The rates of exciton migration and exciton trapping
have been computed using stochastic method to find out the

photochemical efficiency of the dimeric PS II. Three
dimeric PS II units are assumed to form a group, as transfer of the exciton to the
light harvesting bed of the nearest neighbor on either side may only be effective.
A  relationship has been deduced between
the fractions of the reaction centre traps closed and the number of jumps (J)
required by the exciton for trapping. The photochemical efficiency and fluorescence
quantum yield are computed using J as the parameter in an empirical equation.
