Photosynthesis WITHOUT THE SUN

Plants need light to survive. But apparently, that doesn't have to be sunlight.

Perfect timing. I've been trying to figure out a scientific explanation for some underground flora that I created for my sci-fi novels.

WHAT DO YOU MEAN WITHOUT SUNLIGHT!? *clicks immediately*

[basedmusician]

"Photosynthesis" without light is just "synthesis". I'm 13 and this is deep.

[twocvbloke]

Bacteria spends its' life in near darnkess, barely receiving any light from their geothermal vent barfing out magma, then a human comes along with a bright light and makes them feel like a nuke went off... :P

I wrote about this phenomenon in my marine biology degree back in 2010, I'm fairly sure the first photosynthetic organisms were born at hydrothermal vents.

[BobatBG]

Could this possibly explain how cellular life depending on photosynthesis got through snowball earth?

[IntrepidFraidyCat]

So, a geothermal vent is a tiny little nightlight for them as they snuggle together in the nice warm water. 😁

🎶 Ain’t no sunshine where they grow
Only darkness everyday 🎶

[wiros]

Yeah, I know. I use LEDs to grow seedling indoors.
Edit: okay that's freaking cool. Forest lit by magma anyone?

[weatherkidchannel]

Mmmm so photosynthesis without *sunlight* but *earthlight* very interesting.

[Nulley]

What do you do for a living?

GSB1: I eat light from MaGmA

[shados]

The title is great for debunking the sunlight myth, the “photo” in photosynthesis just means light, we can also grow plants without the sun using LEDs.

[ghorabih]

Holy crap. Just finished the video. This is EXCITING NEWS!!!!

[mrjoe]

The way he said "light eating life" is so ominous, because my brain knows he means autotrophs, but my heart says "Ungoliant"

[davidlea-smith]

I conduct research on microbial photosynthesis and biochemistry and was wondering how I missed this research. Then I realised it was published 15 years ago from one of your links. Congrats for making a video reminding us all of this odd discovery. If you want to make a video of the weird hydrocarbon degrading bacteria we found at the bottom of the Mariana Trench at a depth of 11, 000 metres then let me know.

I believe this, I mean... spongebob can go through photosynthesis

[stllbleedng]

It's a pleasure to find out I'm not the only one expanding horizontally 😂

[Pentalaimon]

Green Sulphur Bacteria, GSB-1... well at least it's easy to remember
