Content: If only I mg of the gas enters the leaf per hour, photosynthesis goes on at a certain rate. In this case the increase of intensity of light does not increase in the photosynthetic rate. The light is already present in excess. It is sufficient to utilize I mg of carbon dioxide per hour. He increased the supply of carbon dioxide to 2 mg per hour. The rate of photosynthesis increased at the same light intensity. This shows that the carbon dioxide concentration determine the rate of photosynthesis. Thus carbon dioxide is the limiting factor. ----------------------------
