I have to answer this question for biology for tommorrow, and i really cant find the answer anywhere...so if anyone knows and can tell me thad be great.

Question: Von Helmont was unaware of gases in the atmosphere; therefore he measured only the amount of soil and presumed the plant tissue all came from the water added. Today, we can label molecules with radioisotopes and trace where they travel. Where would we find carbon dioxide labeled with radiocarbon?

is that the whole question? seems like there should be some more background info
and no, i dont think the answer is carbon dating, thats for fossils/how old things are, not where carbon is located

you would find the CO2 going through the Calvin Cycle in the chloroplast. The carbon is being incoporated into organic molecules by carbon fixation. it's being reduced to sugar.

if you ignore the whole first part of the question,then this seems right to me.

killswitch's answer makes a lot of sense if you only use the first and last sentences. Looks good to me.
