Book:  
Photosynthesis (Science Concepts Second) 

From reading reviews about this book it seems to be a good introduction on photosynthesis. It explains the process and the history of discoveries.   The book combines both general reading and research material done in this field. The combination of the facts about photosynthesis and the great photographs makes it a good book to have.  The book also makes you see how photosynthesis is used in the real world by describing materials in life that are dependent on this process. I think it is a good book to have and you can always refer to it if you have any questions about photosynthesis.
