If one may recall nearly half a century ago, there wre small books, Methuen series publishing on special subjects like photosynthesis (C.P. Whittingham) and Plant Respiration (W.Stiles) in the 1950s and have been of great guidance for post-graduate studies in those years. Now great breakthrough have been made with the introduction of isotopes, modern tools and instruments which can project into the cell components and unravel the 'secrets' of plant life, with the results no one book could so completely cover a single topic like photosynthesis or respiration.
