Are there any black photosynthetic chemicals?
I’m working on a speculative evolution moon that was once orbiting a rogue planet. The moon was similar to Europa in that it had an icy shell covering an ocean beneath. Life evolved under this ice ...

Can other sources of energy be used to fuel photosynthesis other than sunlight?
I’m working on a rogue moon that when life evolved it was around a star. Currently it has an ice shell kilometers thick and a deep ocean of liquid water beneath. I already know that chemosynthesis ...

Bioluminescence due to photosynthesis
I'm wondering about how to make my photosynthesising organisms all glow. Basically, I want to make bioluminescence a consequence of photosynthesis, as if the organelles themselves produce light in the ...

How deep underwater can red photosynthesis work?
The Setting:
I have a binary star system.
First star: K5.2V class Orange Dwarf, 60% the mass of Sol, 17% luminosity of Sol, and at 4.5 billion years old. This star is the only one with a planetary ...

Replacing Light in Photosynthesis with Electric Energy
I am currently attempting to construct my alien planet with exotic forms of life that use alternative metabolisms.
I got an idea that I could perhaps somehow replace the photon energy required in ...

Can plants use Light from Aurora Borealis to Photosynthesize?
I am currently designing an alien world and I had the idea that the planet would have constant auroras nearly everywhere due to its host star. At first, I just had some ideas on how that might affect ...

Plausibility of an Ecosystem Based on Giant Diatoms?
In this wildly divergent Earth timeline, a group of diatoms evolved to be up to a few inches across (rather than 2mm or less). With this group presumably developing some similar traits to organisms ...

Could an organism evolve photosynthesis using internal microscopic structures instead of using pigments?
I understand that most animals that look blue don't have blue pigment but instead have microscopic structures that scatter blue light. I was wondering if it would be possible for an organism to ...
