Question

Which of the following is the chief pigment associated with photosynthesis ?

• A. Chl-a and xanthophylls
• B. Chl-a
• C. Chl-a and carotenoids
• D. Chl-b

Answer 1

The correct option is B Chl-a

Chlorophyll A is found in all photosynthetic plants except bacteria. Hence, it is termed as universal photosynthetic pigment. It is also called primary photosynthetic pigment because it performs primary reaction of photosynthesis which involves conversion of light into chemical energy.

Chlorophyll A is the primary pigment for photosynthesis in plants, but the range of light absorption is extended by chlorophyll-b, beta-carotene and other accessory pigments.

Hence, option A is correct.
