are you talking about c3 or c4 because with c3 efficiency is 4.6% whereas in c4 it is up to 6% and when stomata are closed if not what kind of photosynthesis are you talking about
I frankly don’t care, I’m just trying to prevent the game from becoming terrible with unrealistic things being suggested to be added. I’d really prefer if our theory team was more active and was able to torpedo really terrible suggestions like this thread instead of me having to do this with my limited understanding.
to sustain a hollow boned human with just photosynthesis for a couple months with no food just use two relatively flat butterfly type 4 foot long 3 foot tall wings on a planet with low gravity and a dense atmosphere
Also, if it isn’t required, not having it would be selected.
Corals are like a single photosynthetic creature. The animal part keeps the algea from drifting away to darkness. Chloroplast stealers use the chloroplasts as long as they last. It is as if photosynthesising in addition to eating other plants is nice, but using your own resources to build chloroplasts or carrying the gene for building it in all of your cells isn’t worth it.
But the exclusive herbivores would be lighter (not carrying a wing to increase surface area) and outrun the part-time-herbivore/part-time-photosynthesisers. The evolutionary arms race would end in the part time photosynthesiser giving up on running and focusing on building an impenetrable castle, which is constantly being supplied from above. And no tools can be used without movement.
Time really is a circle…
I’ll exit this discussion now for my sanity, and unless another team member participates in this discussion as the opposing voice, winning by “silencing” the opposition doesn’t count.
I don’t know if anyone has said this yet, but maybe fungal (Earth fungi specifically) organisms that are similar to animals could use a matrix of mycelium like a brain?
Also, plants do have some intelligence, and they certainly have senses and can communicate with each other, but their intelligence is limited due to the lack of a centralized nervous system.

plants have the absolute slowest type of nervous system which uses chemicals only
it wouldn’t be antithetical to plantness to evolve something better, but yes, it’s slow
Brains (at the level of individual neurons communicating) use chemicals to communicate too. And also communicate with chemicals.

via action potential, not diffusion
the reason i said this is more “yes plants have a nervous system, yes it is slow but no it could not be used by an animal with it being efficient”
@TristanMisja animal brains use chemicals and electricity not just chemicals
theres slow ways to use electricity, the important thing is action potential vs diffusion
the fastest way to use electricity is have a unicellular tread with a fluid silica wall and make light on one side and absorb that light on the other instead of having an electrical current(AP, AC, or DC) you also have to have the fluid in the cell have a vastly different refractive index from the cell wall
That might be faster if it’s actually viable. But I’m a little skeptical if it actually would be. I mean, how would single “neurons” interact with multiple other “neurons” like they do in brains? Also, action potential is very important. But let me know if I’m misunderstanding something.

here is how it would work in a way i know how to explain it
SETEP ONE. REFRACTION: the difference between the rfractive indexes of the cell wall and the internal fluid must be greater than 3(i think[it might actually be 5])
STEP TWO. INTRACELLULAR SIGNAL TRANSFER: the neurons would, in the presence of a large enough amount of electricity and neurotransmitters, contract two contractile vacuoles (one with luciferin the other has luciferase) sending their contents into the axon to mix(different amounts of electricity and different neurotransmitters result in different wavelengths of light) as the axon would have a reflective wall between it and dendrite to stop a nerve firing multiple times with no input after which the light would travel at the speed the universe operates at within the fluid down the axon to the photoreceptor membrane between the axon and the photoreceptor membrane would have as many types of photoreactive compounds(one for each wavelength) as it has types of neurotransmitter and a different voltage electrical output for each wavelength
STEP THREE. INTERCELLULAR COMMUNICATION: basically the same as with an integrative nervous system except it transfers different voltages along with the neurotransmitters
STEP FOUR. ERRORPROOFING: the neuron must accept inputs from multiple dendrites all at once to fire
Ok, since Hhyyrylainen is closing all the other plant civ threads, I’ll move what I said:
Evolution (kinda):
The creature is a 6 legged manta ray-like thing which is extremly thin and uses photosynthesis to get most of its energy, the rest comes from eating, although it has a very small stomach, it mostly eats hydrogen producing algae which eventually becomes part of its genes, its stomach than splits off in to two at the ends of its “wings”, with its stomachs being able to produce hydrogen it is able to become wider than usual, making eating unnecessary, the whole time its brain gets larger to, and along with that its “stomachs” (which are now just hydrogen bladders) become large enough that it can dive deep down, fill its hydrogen bladders, and than shoot up in to the air and start flying through small flaps of its wings. Eventually flying predators start to hunt them, and one of the photosynthesising rays sees one die in a forest fire, so to stop itself from being hunted, it tries to harness fire, eventually one figures out how to make it, and they start using torches to hunt the predators, scaring the smart ones off that didn’t die, now that their safe they start trying to form a larger colony, when they eventually settle, make basic handaxes and make a house…
Drawing:
Yellow = nervous system, red = muscles (and nerves), white = bone, orange = digestive, purple = breathing, blue = hydrogen bladder.
Math:
At the highest efficiency recorded in plants, 5 square meters would be required to power a human, but this creature is simpler and uses less energy, and the image is 3.5x3.5, which is more than enough.
Any questions?

would an animal that uses an endosymbiotic photosynthesizing prokaryote with a fast version of RuBisCO that was evolved for the purpose of fixing carbon at high speeds to allow it to replicate faster than the other prokaryotes and thus is much lighter so the organism using them can be much more active due to having little enough weight for it’s muscles to handle and it could have non-flexible leaves that are shaped in a way that provides as little resistance as possible when moving or flexible leaves that can be flattened against the body to remove any air resistance from them and the animal only moves at night and when it needs to because it wants to maximize the time it’s leaves get light and it shuts down any non vital organs during the day except ones for sensing predators to maximize glucose production during the day and maximize food consumption at night be more possible than a plantoid that could evolve from an earth plant
Man, I am sorry I created this thread, I had no idea it would cause this much headache to the devs. What in the world happened here? xD

Well considering 2 other threads just got locked for being too similar, I think the plantimal threads were inevitable, it isn’t your fault lol
