A researcher uses a radioactively-labeled carbon dioxide molecule to evaluate photosynthetic rate. In her experiments, the researcher finds adequate consumption of water, generation of oxygen and NADPH production, but no change in plant mass. What is most likely the dysfunctional system in the plant (PI, PII, Calvin Cycle, ATP generation)? Explain in detail why it is one as opposed to the others.

Plants transfer carbon in the carbon cycle a. through assimilation of carbon from the soil. b. when carbon transpires from their stomatae. c. when they are eaten by animals. d. through fixation of carbon in the soil.plants transfer carbon in the carbon cycle a. through assimilation of carbon from the soil. b. when carbon transpires from their stomatae. c. when they are eaten by animals. d. through fixation of carbon in the soil.
