Content: This happened because higher light intensity will provide higher photon energy to excite electrons of the chlorophyll. Therefore, when this happens, there will be higher amount of energy in the form of ATP to produce a higher amount of glucose and oxygen. Thus, we can conclude that the rate of photosynthesis is higher at the higher light intensity. These explained well on the behavior of graph 8.22 which we can say that the graph shows rate of photosynthesis is directly perpendicular to the light intensity. The graph 8.22 was plotted to show the relationship of light intensity on the rate of photosynthesis. This graph is used to support the graph 8.21 produced earlier so that the result obtained can be claim to have a high certainty and it is proven to be right. Plus, from the graph 8.22, we can see that the higher the light intensity, the higher the rate of photosynthesis which is compliment to the theory. This means that both graphs support the theory of light intensity as one the factors that affecting the rate of photosynthesis whereby any decrease in distance or increase in light intensity, will cause to an increase on the rate of photosynthesis. Conclusion
Hence, based on the discussion above, we can conclude that in any increase of the distance of the lamp bulb to the base of the beaker will cause in the decrease of light intensity. Then, with the increase of light intensity will cause in the decrease in the time taken for the leaf discs to float on the surface of the solution which represents the increase of the rate of photosynthesis.
