Based on a variety of experiments, it is known that the rate of photosynthesis is highest when wavelengths of light between 400 and 500 nm are used, and when wavelengths around 700 nm are used. What does this indicate about the relative importance of chlorophyll a and b in photosynthesis?
A. Reflection of light by chlorophyll a and b is essential for the process of photosynthesis. B. Absorption of light by chlorophyll a and b is essential for the process of photosynthesis. C. Chlorophyll a and b are much less important than other pigments in the reflection, absorption and transmission of light relevant to photosynthesis. D. Transmission of light by chlorophyll a and b is essential for the process of photosynthesis.
