Question

Quizplus · Accepted Answer

Chlorophyll a and chlorophyll b differ in the wavelengths of light they absorb most efficiently. Chlorophyll a absorbs most light in the blue to violet and red parts of the spectrum, while chlorophyll b absorbs most light in the blue and orange parts of the spectrum. This difference in absorption spectra allows plants to utilize a wider range of wavelengths for photosynthesis.
