[MODERATOR NOTE: I think we've had enough conversation about CO vs CO2 and respiration. After this post the topic is closed. - Mike Substelny, DML pinch-moderator] We're going way off topic now :-) But note I said "during respiration" which is what a plant does in the absence of light. During respiration, a plant consumes oxygen and emits carbon dioxide. (going back to my GCSE Biology, many moons ago - did I get it right?!)

It is synthesized into Oxygen which is "exhaled" by plant-life. Indeed, I heartily agree with your further observations.
