Birth of Planet Earth: Photosynthesis in a Chromatophore

Birth of Planet Earth tells the twisted tale of our planet’s origins.
Scientists now believe that our galaxy is filled with solar systems, including up to a billion planets roughly the size of our own. The film employs advanced, data-driven, cinematic-quality visualizations to explore some of the greatest questions in science today: How did Earth become a living planet in the wake of our solar system’s violent birth? What does its history tell us about our chances of finding other worlds that are truly Earth-like?
Early one-celled bacteria could survive by capturing the energy of sunlight. Later, using similar chemical machinery, plants evolved; they helped re-oxygenate the planet and stem the loss of water. Captured sunlight drives a chain of processes, transforming the energy into more stable forms at each step, eventually producing molecules of ATP – the universal currency of life on Earth – with which the bacteria can feed, locomote and reproduce.
