Following the elucidation of the photosynthetic apparatus of purple bacteria at atomic resolution, researchers have been able to answer this question through the application of quantum physics. A closely tuned interplay between geometrical arrangement and the electronic structure of chromophores allows bacteria to achieve the unique functionality of their photosynthetic apparatus. Abstract Biological cells contain nanoscale machineries that exhibit a unique combination of high efficiency, high adaptability to changing environmental conditions, and high reliability. Recent progress in obtaining atomically resolved structures provide an opportunity for an atomic-level explanation of the biological function of cellular machineries and the underlying physical mechanisms. A prime example in this regard is the apparatus with which purple bacteria harvest the light of the sun. Its highly symmetrical architecture and close interplay of biological functionality with quantum physical processes allow an illuminating demonstration of the fact that properties of living beings ultimately rely on and are determined by the laws of physics.
