(d) In photosystem-I, the photocentre is a special chlorophyll-a molecule called |
, which is active in both red and far-red light, while a very small amount of special from of chlorophyll-a called 
, constitutes the reaction centre of photo system-II. PS-II is inactive in far-red light (beyond 680 nm).Next Question :
