Sep 25, 2012 · 61) Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. Why are they different? A) Green and yellow wavelengths inhibit the absorption of red and blue wavelengths. B) Bright sunlight destroys photosynthetic pigments. C) Oxygen given off during photosynthesis interferes with the absorption of ...

The action spectrum of photosynthesis does not match exactly the absorption spectrum of any one photosynthetic pigment, including chlorophyll a. Only chlorophyll a participates directly in the light reactions, but accessory photosynthetic pigments absorb light and transfer energy to chlorophyll a.

Notice that the photosynthesis action spectrum has a wider left peak that the chlorophyll absorption graphs. It doesn’t bottom out until 550 to 600 nm. What does that mean? Propose an explanation for this. Graph 2: create a graph in your lab book. Use the data from the table below to make an absorption spectrum graph for caratenoids.
