Question

What is the function of accessory pigments like carotenoids in photosynthesis?
Options
A Broaden the spectrum of light absorbed
Correct Answer
B Directly fix carbon
C Store solar energy
D Split oxygen molecules
Correct Answer

Option A is the correct answer.

Detailed Explanation

Accessory pigments absorb wavelengths of light that chlorophyll cannot (like blue-green and green) and transfer that energy to chlorophyll. This expands the range of light that can be used for photosynthesis.

Hint

They help capture more of the light spectrum and also protect chlorophyll from photo-damage.
