WebTo explain this principle, Blackman gave the following illustration which is also shown diagrammatically in Fig. 11.24. Suppose a leaf is exposed to a certain light intensity which can utilize 5 mg. of CO 2 per hour in photosynthesis. If only 1 mg. of CO 2 enters the leaf in an hour, the rate of photosynthesis is limited due to CO 2 factor.
