what do you know about this? I've searched the internet and it seems as if the process is, indeed, reversed at night time.

the Thais do not keep plants in their bedroom for this very reason, so there's been discussion and even bets made.

so, my dear science geeks, does photosynthesis reverse at night time or are the Thais just crazy?

Everybody knows that photosynthesis is reversed at night. The chlorophyll breaks down and emits photons.

clearly, not everybody knows.
now, if you'll pardon my ignorance and/or failure to comprehend, but when you say chlorophyll emits photons, are you in fact saying that the plants emit light?

if you are not going to contribute anything of value, please do not post.
in the first post, I made it obvious that I have already searched and I am looking for answers from someone with actual knowledge.

.... ^^^^ ....
Are you offering to pay me the usual researchers fees for looking stuff up for your lazy ass?



Have fun, play safely, and don’t play with fire!

i don't know if it's an exact reversal of photosynthesis...

but look for the "dark reactions" of photosynthesis.

obviously i don't know the details well enough to explain it.

And cross-reference it with dark energy. Dr. Michio Kaku of City University of New York has done quite a bit of work in this area.

I'm waiving my usual researcher's fees this one time .... but from now on you're on your own.

I did a search on plants absorb oxygen at night and found lots of stuff, including this site, where they had a quick explanation (but it's not "the reversal of photosynthesis"):

http://www.copperwik...hp/Oxygen_Cycle

Plants mark the beginning of the oxygen cycle. Plants are able to use the energy of sunlight to convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. During the day, plants hold onto a bit of the oxygen which they produced in photosynthesis and use that oxygen to break down carbohydrates. But in order to maintain their metabolism and continue respiration at night, the plants must absorb oxygen from the air and give off carbon dioxide just as animals do. Even though plants produce approximately ten times as much oxygen during the day as they consume at night, the night-time consumption of oxygen by plants can create low oxygen conditions in some water habitats.
How many times do I have to tell you kids to quit perning in that gyre?
