Human Plants

[mith]

well you said it would be dangerous to depend on photosynthesis if it got dark, but plants store lots of starches and eat off that reserve. Humans can lug around balls of fat too.

This question is really strange, I never thought of this. I suppose we could make our own food through photosyntethis but we would still be dependent on water(maybe we could grow a root ) and minerals. Furthermore, a plant can syntethise just about anything. Out of 20 aminoacides, we can only syntethise 12-the other 8 we need from food(if you want i can name them too )
By the way, a plant can only survive for about 48 hours without sunlight. I did an experiment a few weeks ago and in order for the plant to consume all the starch it had accumulated it had to be let in a dark place for 48h. The kingdome Animalia has evolved so well because we can live in dark places for a long time(you can't take sunlight in a backpack, but you can take food)

Being able to photosynthesize doesn't mean we lose all ability to digest food. I'm thinking of it more as a supplement.

The average is 30 days for food.

Maybe you meant going without water? I know that one is about a year you can go.

Err, I got that backwards, sorry. Checked my books. The average HEALTHY person can go 30 days w/o water and 360 days w/o food.

This would depend upon the ammount of stored food which would deffer from plant to plant,but this would not make considerable defference in terms of days, I think .
So, as I said I am also thinking of this as a suplement! But I wonder which part of our body should we expose in order to photosynthesize???
keeping only our limbs exposed in daytime , would provide an adequate food suplement , this is better from some other pt. of view, Do U agree???

Most of us work under shelters do , we have to expose much of our body and tke sun bath daily for some specefic time, but in some countries it may lead to skin cancer, so
there this will not work!!! There they may use some anticancer creams which don't affect the photosynthesis adversely, or best way take sunbath under ultraviolet proof glasses - I think , there is some thing that absorbs those harmful radiation, M I correct???

I don't know if anyone has mentioned this already but...

The minerals found in tap water if well enought to cover the needs of an ordinary plant.

Plants doesn't really spend alot of energy moving around, a walking plant would need lots of leaves or it would starve to death.

Oh I didn't notice this, probably because I am looking at this as a suplent which will help reduse the severity of food shortage in future, [ imaginary today , but it may be possible tomorrow].
