Which one of the following is not a photosynthetic pigment?

Q. Which one of the following is not a photosynthetic pigment?

A. Chlorophyll
B. Phycobilin
C. Carotenoid
D. Anthocyanin

Answer: Anthocyanin

A photosynthetic pigment (accessory pigment; chloroplast pigment; antenna pigment) is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis.

Green plants have six closely related photosynthetic pigments (in order of increasing polarity):

• Carotene - an orange pigment
• Xanthophyll - a yellow pigment
• Phaeophytin a - a grey-brown pigment
• Phaeophytin b - a yellow-brown pigment
• Chlorophyll a - a blue-green pigment
• Chlorophyll b - a yellow-green pigment
