Plant Oxygen production question?

[nao57]

So people say that plants don't make oxygen at night? Or at least I'd heard people say that. That it shuts down or is changed somehow to not be the same kind of gases.

But I wonder if that is true, or wrong information?

The reasoning is; people and animals don't just stop breathing at night. So it would seem like plants...wouldn't stop breathing either, unless its a different kind of chemical reaction that produces something but maybe just not oxygen?

Is this wrong information (for most plants)?

There was a NASA study in the 80s... (before NASA was run by leftists), that showed also that there were 5 to 10 different types of plants that could be put inside houses that would both clean the air very well and still produce oxygen without sunlight. That study is reliable. And it includes 'mother in laws tongue' or snaketongue in the list of those plants. So that study is helpful also for people wanting to make the air in their house better...

But I don't know for sure if they changed their ideas about other plants not on that list and how they react or don't react to making oxygen at night?

And curious what you think?

I thought photosynthesis occurs with a certain amount of light so I think moonlight can be sufficient.
Most plants certainly don't need direct sunlight. Any ambient light of sufficient candle power can cause the process.

We cannot compare plants with people and animals, their system is way different form one another. Example: green plants take in carbon dioxide (during the day) and use it as a food source and only takes in oxygen at night, people and other animals cannot.

During the day green plants make their food and give off oxygen this prosses is called Photosynthesis and is the process by which green plants (and certain other organisms) transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

At night these green plants will "shut down" meaning they are in rest and are no longer making food (Photosynthesis) BUT, this is when they take in oxygen and consume "eat" the food they made during the day.

As for the NASA study, ALL green plants need light. Without light there is no Photosynthesis, and the plants will die. Even the Dracaena Trifasciata (Snake Plant, Mother-in-law's tongue, Saint George's sword, viper's bowstring hemp) needs light.

You can find good bit on Photosynthesis online, just use Google Scholar not regular google.

Also, when I get a minute, I'll try to post some information on Photosynthesis that's in of the Ball seed company's greenhouse books I have.
