Explain this then
Comment on That's just science
BCsven@lemmy.ca 1 week agoPlants look green because the green spectrum has a lot of energy, and to stop over heating and leaf burning and messing with the delicate photosynthesis, plants reflect or let green mostly pass through and only use about 20% of green soecturm energy, while mostly use all of red end and blue end… At least that’s what I heard on a science show.

Because evolution isn’t actually guided and is really just a process of mutation, reassembly (for sexual species), then checking to see if it works well enough to pass genes on. Apparently red leaves work for that plant

We have diverse geography, and genetic diversity. Obviously this plant worked out a way to use the high energy of the wide green ranhe, without overcooking itself. But if you compare all plamt leaves and grasses of plant life green is the most common.

And why does the green spectrum have a lot of energy?
BCsven@lemmy.ca 1 week ago
I’d have to go back and find the science article, but it was something about sunrise, sunset which would often provide end of spectrum red or blue, while full daylight provided a lot of green light spectrum. Plants having to balalnce processes in full spectrum would overload/oveheat so they evolved to reflect or transmit through 80% of that spectrum.
They mostly use red and blue for photosynthesis because those seem more steady during daylight hours in various seasons and hours of the day. Cloudy day still gets infrared end through etc.
The green overlaps into red and blue zones. Its not so much that it is higher energy than blue, but a wider amount of spectrum total energy the plant wants to avoid.
