Question

Plants produce carbon dioxide as a product of cellular respiration. But you know that plants release oxygen, not carbon dioxide. Develop a logical argument for how this is possible.

Answer 1

Carbon dioxide is released during respiration but used up during photosynthesis. The reason that plants release oxygen is because the amount of carbon dioxide released by the plants is, for the most part, used in photosynthesis; however, all of the oxygen produced is not used in respiration. Thus, the net outflow of gas from a plant is that of oxygen.
