Figure 10.1
-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 light.
D) Other pigments absorb light in addition to chlorophyll a.
E) Aerobic bacteria take up oxygen, which changes the measurement of the rate of photosynthesis.

Quizplus · Accepted Answer

Other pigments, such as chlorophyll b and carotenoids, absorb light in addition to chlorophyll a, resulting in a broader action spectrum for photosynthesis compared to the absorption spectrum of chlorophyll a alone.
