Reactions explained how the human body would be different if it could photosynthesize like a plant. The video also explains how photosynthesis works, and the basic reasons why humans don’t do it.
The sun shines a massive amount of energy onto the Earth’s surface every day. What if humans could take a cue from plants and use sunlight to make their own food? From chloroplasts to carbon dioxide, Reactions creates a hypothetical photosynthetic human and gives a quick crash course on the chemistry of photosynthesis.
