Why Are Plants Not Black?

I’m curious as to why it isn’t black, because I’d expect these animals, who live by harvesting sunlight, to absorb all wavelengths of light. They may not, however, do so. Some of the light is reflected back to them. Then there’s the most important part: green light. Previously, nearly all colors were a mystery from a scientific standpoint. It’s worth noting that Green is a color. What is the source of this emerald hue? Wouldn’t it be more appropriate for plants that feed on this light and conduct photosynthesis, or the conversion of light into energy, to swallow it entirely if the solar spectrum reaches its maximum value in green?

Plants absorb almost all photons in the red and blue areas of the light spectrum, but just 90% of photons in the green region. We would see them as black if they consumed 100% of them. Since they spit 10% of the green light, we see them as green. This was one of the most perplexing topics for scientists, and a solution was recently discovered. Scientists discovered that plants did not consume all of the green in terms of energy production when studying the mechanism of photosynthesis in plants. As a result, scientists created a model of the photosynthesis process in plants to better understand why. This model not only explains why plants waste green light, but it also reveals an evolutionary theory that may apply to all photosynthesising species in the universe. If you look at the leaves of plants in the wild, you’ll notice that the amount of light falling on them varies during the day. Consider how this transition occurs on a regular basis in the leaves of all plants in a forest. The creation of noise in the energy they obtain from the sun is obvious for these creatures who survive by collecting the energy in the light. Plants change the color of their leaves to optimize photosynthetic activity and minimize noise. Reflecting some parts of the solar spectrum will provide protection against continuously changing solar energy. Those areas seem to be mostly green.

To summarize, rather than being more effective, it sacrifices the most valuable parts of the sun’s light in order to be more stable. Since it seems that in essence, stability takes precedence over efficiency. They discovered a model that is so universal that it produces the same result in other photosynthetic species. The same conclusion is reached not only by plants, but also by other living things that perform photosynthesis. Salt Lake, for example, is reddish in color due to the presence of halobacterium. They are photosynthetic, much like trees.
