Demonstrate the effect of changing light levels on electron transport in photosynthesis as measured by oxygen production. Describe an experiment that demonstrates that carbon dioxide is utilized during photosynthesis. Introduction. The equation for photosynthesis is: CO2 + H2O ( (CH2O)n + O2 . In this equation, (CH2O) represents the general ...

At low to medium light intensities the rate of photosynthesis is proportional to light intensities, at high light intensities the rate reaches a plateau. Planning. Photosynthesis is the process used by plants and some other organisms to produce all their own organic substances (food), using only light energy and simple inorganic substances [1].

We have found, for example, that the rate of photosynthesis in the presence of 4 layers of Filter 298 is the same as that found in the presence of one layer of Filter 210. Clearly, other combinations are possible. Science & Plants for Schools: www.saps.org.uk. The effect of light colour and intensity on the rate of photosynthesis: p. 1
