Ive searched on-line, and many sources have gotten the same answer as my science experiment, but they have not answered WHY. So, my question is WHY does extra co2 help plants reproduce better? I found that it does, but WHY??
Plants need CO2
as the source of carbon for photosynthesis, the process by which the make sugars and other big molecules. If thereís no CO2
, the process stops altogether. Itís not surprising that a little extra CO2
can speed it up a bit, just as supplying a little extra of any nutrient tends to speed up growth.
