Practice Questions

Photosynthesis (Question 1 of 30)

Which pigment directly participates in light-dependent reactions of photosynthesis?

A

Chlorophyll-b

B

Chlorophyll-a

C

Xanthophyll

D

Carotene

NCERT Explanation

Chlorophyll-a is the primary pigment in the reaction centers of photosystems (PS-I and PS-II) and directly participates in the light-dependent reactions by absorbing light energy and exciting electrons. Accessory pigments like chlorophyll-b, xanthophyll, and carotene transfer absorbed energy to chlorophyll-a but do not directly participate in electron excitation.
