According to this article, the frequency of stomata increases with an increase in the intensity of light. What I inferred from this is, since the rate of photosynthesis increases at higher light intensities, more C02 is is required and hence the frequency of stomatal openings increases.
I know that the Light Harvesting Complexes inside chloroplasts use light to release electrons, which are then subsequently used in photophosphorylation. If we compare the process with the photoelectric effect, we shouldn't see an effect of the intensity of light, but instead we should see changes for different frequencies(which we already do).
So how does the rate of photosynthesis increase with higher light intensities? Is the mechanism of light absorbtion by LHCs similar to that of a photoelectric cell?
