AP BIOLOGY

Detailed explanation-1: -Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

Detailed explanation-2: -So, Chlorophyll a is the chief pigment of photosynthesis and others (i.e., chlorophyll-b, xanthophyll and carotenoids) are accessory pigments.

Detailed explanation-3: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.

Detailed explanation-4: -Chlorophyll a is the primary photosynthetic pigment as it converts light energy into chemical energy.

Detailed explanation-5: -In plants, chlorophyll a and chlorophyll b are the main photosynthetic pigments. Chlorophyll molecules absorb blue and red wavelengths, as shown by the peaks in the absorption spectra above.
