I Don't Understand Quantum Physics and Farming

When I grew up, the planetary model of the atom was standard. Sets of electrons revolving around a nucleus of neutrons and protons, that was it. I've always been interested in science, so I've read enough to recognize some of the terminology of quantum physics. Unfortunately, as I age my capacity to absorb this stuff seems to have shrunk. I consoled myself by thinking quantum physics had little connection with my life. But this piece (actually not the original one I saw, which I think was in Scientific American, or maybe online--my memory for my reading is shrinking as well) on how quantum physics works with chlorophyll to capture energy really upsets my consolation.
