Photosynthesis cannot take place without chlorophyll. Step by step, Prof. Dr. Tausch of the Bergische Universität Wuppertal explains the functions of chlorophyll. The chemical process is illustrated with the Photo-Blue-Bottle experiment. It simulates energy conversion and chemical transformation processes within the complex natural processes of photosynthesis and cellular respiration. Furthermore, the video comprises animations which help visualize the underlying chemical reactions.
