Looking out at the plants surrounding us, it might seem as if there is not much going on in their lives. But, if we were to zoom in on these plants and gaze into their interior, we would find the most intricate and complex biological processes that we are still far from fully understanding. One process that we can observe is the light dependent reactions of photosynthesis where plants harness the energy of the sun, converting it into a form of usable energy. Today, we will be explore how this process works.
