Photosynthesis

Abstract

This chapter is concerned with the way in which biological systems have been able to adapt their specific need to synthesise organic materials to the physical properties relating to light, which is a form of energy. Again, some detailed biochemical information is given to show something of the nature of the complexity of the chemical manoeuvres which allow organisms to utilise light energy. Here, as well, investigators have been particularly ingenious in their experiments to test the various hypotheses put forward. What you are presented with here is an outline of a working model for photosynthesis and from time to time some of the evidence for this model is given. The model is still incomplete and no doubt aspects will be changed as further evidence is obtained.
