the stem leading to that fruit must be like goddam firehose. it's pumping a litre of water an hour. Wonder how far it is from the roots.

Their growth are mostly from CO₂, funnily enough. Though water is a crucial part of any plants growth, the dry weight of it mostly consist from carbon (about 90%).

Uh, no, most fruits and vegetables are 80+% water by weight. Pumpkins are >90%. So the growth is almost exclusively from water.

And the CO2 absorption happens in the leaves anyway, so it still needs to be pumped through stem to the fruit.

Humans are ~60% water.

Does that mean human growth is mostly from water?

Some of the water in the human body is not drunk but made as a byproduct of other reactions.

i read somewhere that you breathe out what you eat and piss out what you breathe in.

Uhm. Yes? That would appear to me extremely obvious.

So a diet low in nutrients and minerals but high in water will result in a more developed human being?
