Respond to the following questions.  Why might it seem surprising that green light can drive any photosynthesis, given that chlorophyll, the major photosynthetic pigment, is green? How can it do this? Suppose that CO2 levels were to rise to 600 ppm, which in fact probably was their level about 300 million years ago. What effect would you suppose that might have regarding competition between C3 and C4 plants? In other words, which of the two kinds of plants would the change favour and why?
