C4 article has better intro.
The intro at C4 tells me that there are three mechanisms which to me is a better intro.
C4 carbon fixation is one of three biochemical mechanisms, along with C3 and CAM photosynthesis, functioning in land plants to "fix" carbon dioxide (binding the gaseous molecules to dissolved compounds inside the plant) for sugar production through photosynthesis.

I removed the citation need from the paragarph: "C3 plants lose up to 97% of the water..." because the wikipedia article on Photorespiration addresses these things and citations and references can be found there. Linkato1 (talk) 16:20, 28 August 2019 (UTC)

The article, as currently written, contains inaccuracies regarding carbon dioxide concentrations. Hot dry days cause C3 plants to close their stomata, starving the plant of CO2. This in turn causes O2 concentrations within the plant to exceed that of CO2, which causes photorespiration to occur. The result of this process is no food production and reduced carbon fixation. If CO2 is the cause of climate change, and climate change is causing hot dry days, then this is another example of CO2 accumulation reinforcing itself. 35.9.40.68 00:08, 30 August 2007 (UTC) |
