Low Wavelength and Photosynthesis

Click For Summary
SUMMARY

Plants can utilize low wavelength ultraviolet light for photosynthesis, with intriguing results observed when x-rays and gamma rays are applied. The discussion highlights that wavelengths around 650nm contribute to photosynthesis rates comparable to those in the 350nm-450nm range. Misinterpretations of graphical data regarding wavelength scales were clarified, emphasizing the importance of accurate source attribution in scientific discussions. The conversation also touches on the impracticality of using high-frequency waves for photosynthesis when more accessible radiation options exist.

PREREQUISITES
  • Understanding of photosynthesis mechanisms
  • Knowledge of electromagnetic spectrum and wavelength ranges
  • Familiarity with scientific data interpretation
  • Awareness of proper citation practices in scientific research
NEXT STEPS
  • Research the role of ultraviolet light in photosynthesis

I realize this is not a biology forum.

Check out the attachment.

As expected, plants can use some low wavelength ultraviolet light for photosynthesis.

However, the photosynthetic process seems to go nuts when x-rays are used. This is the first time I've ever heard of this. Even gamma rays seem to produce good results.

Is this some sort of survival mechanism for a post-apocalyptic nuclear wasteland? :p

Or more likely, a throwback to a time when the Earth had a thinner atmosphere? (might be way off here). Would the lower wavelengths cause mutagenic effects?

Seeing as how wavelengths around 650nm seem to contribute to a rate of photosynthesis comparable to 350nm-450nm range, producing these high frequency waves would obviously be impractical and wasteful when there's plenty of good radio and microwave spectrum radiation lying around. :p

Has anyone read any studies about this?

Please note that it is standard practice in science (and many other places as well) that when you take something like this, you must attribute the source! It is "bad manners" in science to take a figure, especially when it has experimental data, and not cite the source.

I don't really have a source, sorry. This graph came included in the course materials for a physics course.
 
Then you should make sure you clarify that THAT is where you got it, and that you cannot attribute the source (it is a very bad form for your course material to not cite where they got something like this). Or else, if the owner of this graph happened to see it and there's no mention of any attempt at crediting the work, that does not make for a very good image of this forum.

BTW, you are reading the figure all wrong! The top part of the figure is simply a scale of the different wavelengths. The bottom graph is not related to the top. Look at the horizontal scale of the graph. The wavelengths are in the hundreds of nm. x-ray has wavelength LESS than 1 nm!

Zz.
 
D'oh. That's embarrassing. The graph is only for visible light.
