Question

chlorophyll b absorbs green wavelengths of light that chlorophyll a cannot absorb. in this respect, chlorophyll b acts as multiple choice a light absorber in the green light. an energizer for photosynthetic bacteria. a more efficient pigment. an accessory pigment.

Explanation:

Chlorophyll b absorbs light wavelengths that chlorophyll a can't, and functions as an accessory pigment to enhance light - harvesting in photosynthesis. It doesn't act as a light absorber uniquely in green light (plants reflect green light mainly), nor as an energizer for photosynthetic bacteria specifically, and it's not more efficient in an absolute sense compared to chlorophyll a in all aspects.

Answer:

D. an accessory pigment
