Would it be possible to put chlorophyll in the cells of humans so we could capture sunlight?

>> No.1277103

we aint plants niga

>> No.1277111

I doubt it would be impossible but there's a very good reason plants are not particularly mobile.

>> No.1277112

plant cells. animal cells. nuff said.

>> No.1277120

I think the melanin would absorb it before it would penetrate to the chlorophyll... unless you are implying we replace our melanocytes with clorophocytes.

Just coined a new word. You heard it here first, /sci/entists!

>> No.1277125

>>1277112
Both plan and animal cells are eukaryotic.

We would replace our melanocytes with clorophocytes. Would it work then?

I want plant hair

>> No.1277133

In theory it might work but what do you do about controlling the amount of intake of food you get other then hiding from the sun?

The more you go outside the fatter you get?

>> No.1277135

>>1277133
That would not really be a concern.

>> No.1277139

>>1277094
yes

>> No.1277144

If its possible, why dont we do it? It would solve world hunger.

>> No.1277147

>>1277133
how about keeping the melanocytes but having the ability to expand and contract them to regulate the amount of sunlight received

>> No.1277149

you should start slowly, practice with chloroform

>> No.1277151

>>1277135
How? explain.

>> No.1277155

The chloroplast can only produce carbohydrates, so I assume humans would feel less compelled to eat foods with high carb content. We would require a fuck load of water, unless we could take the water produced by cellular respiration and put it inside of a perpetual recycling loop.

Btw guis, plants undergo cellular respiration AND photosynthesis. They produce O2, CO2 and water.

>> No.1277156

>>1277094
There is that sea slug that eats algae to absorb their chloroplasts and then uses that to photosynthesize. It probably would not be possible to do with today's technology.

>> No.1277157

>>1277147
It would not be necessary. You would capture pitiful amounts of energy relative your normal metabolism.

Simply capturing sunlight isn't the only thing we need... we also need carbon dioxide. Oh that was easy.

Next our body needs a method to transport the newly created sugars around to where they are needed... like a circulatory system. Done.

Finally, we would need a method to "burn" those simple sugars in our cells to convert it back into useful energy... like mitochondria. Check.

Sounds like we have a plan!

>> No.1277173

IIRC chlorophyll contains cobalt, which if in high enough concs is lethal to humans, so yeah, our body has very shitty cobalt regulation = we dead.

>> No.1277176

>>1277151
Ever notice how plants
1) don't really move
2) have almost no caloric content?

Yeah.

>> No.1277193

>>1277094
also you would become much more energetic because of the constant feed of O2 to your body from the chloroplasts. your body would become ridiculously self-sufficient.

Wouldn't we have a problem with eating large amounts of plants then? Last I checked, vegans can live very successfully without succumbing to heavy-metal poisoning.

>> No.1277210

>>1277094
you wouldn't be a plant you'd be half and have taking characteristics from both being a plant and animal.

>> No.1277207

>>1277193
No, it wouldn't. The body requires far more O2 than the surface area of your skin could possibly generate.

>> No.1277205

>>1277151
To be less pithy than the previous anon, photosynthesis doesn't produce energy very quickly nor does it produce very much. It takes upwards of a year for a plant to store as much energy as an animal of similar mass uses in a day.

>> No.1277206

>>1277176
not to mention the FUCKING HUGE SURFACE AREA OF THE LEAVES!!!
in short, chloroplats can't generate enough energy for a human to lsurface due to ridiculous small surface area

>> No.1277215

overkill
we already capture light - heard of vitamin d?

So we need to slim down to decrease our volume:surface area ratio. We also need to increase our surface area... let the ritual skin stretching begin!

not capture, use to sinthezise
and vitamin D isn't exactly oxygen and sugars, now, is it?

He's not saying it would replace breathing, but it would assist it.

>> No.1277244

>>1277223
not so much skin stretching and thinning as exponentially increasing the area, beyond the limits of what the tissue can support
also, standing very still and breathing very little.
mammal metabolism uses a fuckton of energy and oxygen, but hey, it's a small price for titties!

that's because we CAN'T break down chlorophyl. or cellulose, fo that matter
That's right, most of the plant matter you eat goes straight down your toilet, unused

which is why veganism is retarded
oour whole digestive system is suited for omnivorism, especially for eating meat, roots and fruits, in that order
just compare you jaw and teeth's structure to that of an herbivore. not to mention lack of a functioning ceacum ou multi-chambered stomach to harbor the symbiotica bacteria necessary to process cellulose. no animals can process celullose by themselves
what cows actually eat is not the grass, but the residue left by the bacteria in their stomachs; and they have to vomit it up, re-chew it and re-swallow it several times before they can even eat that

Fucking pandas. Digestive system of a carnivore, yet eat bamboo all fucking day. Why the hell are they so fat?!

>> No.1277376

>>1277336
They're not fat. Also the reason they're famously unlikely to breed is that the bamboo provides so little energy that if they stopped eating long enough to have sex they might not be able to make up the deficit and starve to death a few weeks later.

>> No.1277379

>>1277336
one of the reasons they are going exctinct. they became so specialized in eating bamboo, that when the bamboo dies, they die with eat
also, they eat a shitload of bamboo shoots, it's pratically all they do the whole day (like pretty much every herbivore spends most of the day eating). also, bamboo is a fast growing soft-bodied (yeah, I know, not a real technical term, but you know what I mean) plant, and has a smaller content of cellulose per unit of mass than the same amount of, say, tropical tree leaves. they are also richer in protein

>> No.1277380

this is why cooking is key, break down that cellulose.

actually pretty lean, as bears go

Also the reason pandas cover their eyes when they sleep is to protect them from ground-dwelling leeches. For such cute animals, pandas live depressing lives.

>> No.1277413

>>1277380
actually, cooking it for long enough to break the cellulose would turn leaves into a disgusting paste. chewing like a motherfucker is a better option, and is why hoorses and cows have fucking huge, evergrowing teeth.
what cooking actually breaks is sugars, like starch
