Examples of accessory pigments for photosynthesis are:

• A. Chlorophyll b and carotenoids.
• B. Chlorophyll a and chlorophyll b.
• C. Chlorophyll a and carotenoids.
• D. Carotenoids, chlorophyll b and chlorophyll a.

Answer: (A)

Verified step by step guidance

1. Understand that accessory pigments are molecules in photosynthetic organisms that assist chlorophyll a by capturing additional light energy and passing it to chlorophyll a for photosynthesis.
2. Recall that chlorophyll a is the primary pigment directly involved in the light reactions of photosynthesis, while accessory pigments broaden the spectrum of light that can be used.
3. Identify common accessory pigments, which include chlorophyll b and carotenoids; these pigments absorb light wavelengths that chlorophyll a does not absorb efficiently.
4. Recognize that chlorophyll b acts as an accessory pigment by transferring the absorbed light energy to chlorophyll a, and carotenoids protect the plant by dissipating excess light energy and also assist in light absorption.
5. Conclude that the correct examples of accessory pigments are chlorophyll b and carotenoids, as they complement chlorophyll a in photosynthesis.
