Due to slight difference in their _, the chlorophyll a and chlorophyll b show slightly different _.

Explanation

Option A is correct.Due to a slightly different chemical structure, the chlorophyll a and chlorophyll b show slightly different absorption spectra. The main difference between chlorophyll a and chlorophyll b is the presence of a 3-methyl group on the porphyrin ring in chlorophyll b. This 3-methyl group absorbs light in the blue-green region of the spectrum, which is why chlorophyll b appears blue-green. In chlorophyll a, the 3-methyl group is replaced with a formyl group. This formyl group absorbs light in the red region of the spectrum, which is why chlorophyll a appears red. The different chemical structures of chlorophyll a and chlorophyll b result in slightly different absorption spectra. Chlorophyll a absorbs more blue-green light than chlorophyll b, while chlorophyll b absorbs more red light than chlorophyll a. This means that they absorb slightly different wavelengths of light.The slightly different absorption spectra of chlorophyll a and chlorophyll b allow them to work together to absorb a wider range of wavelengths of light. This is essential for the efficient conversion of light energy into chemical energy.
