Fact for the day: plants are incredible. 🌱 they look green to us because they are absorbing deep blue and red light, which leaves the rest of the spectrum reflected back at our eyes. The pigment responsible (chlorophyll) becomes "excited" by the energy present in single photons from sunlight. The excited electrons in the pigment would otherwise release their captured light energy as heat (like your skin after a beach day) if plants weren't adapted to harvest that energy, and convert it to something useful. So instead, the excitement (the energy now present in this electron) is used to build larger molecules, such as sugars and starch. It's interesting to consider that bacteria also have the ability to conduct the same kind of light harvesting reactions as plants, with the added bonus of being a single cell... does anyone see a potential technology here?
