Xanthophylls 3. Yellow color, helps in light absorption and protection. D. Carotenoids 4. Yellow to yellow-orange color, aids in light absorption and protection.
Options
- AA - 4, B - 2, C - 3, D - 1
- BA - 2, B - 1, C - 4, D - 3
- CA - 3, B - 4, C - 2, D - 1
- DA - 4, B - 3, C - 1, D - 2
Correct answer
A. A - 4, B - 2, C - 3, D - 1
Step-by-step solution
A - 4: Chlorophyll a is blue-green and absorbs light maximally at around 430 nm (blue) and 662 nm (red). B - 2: Chlorophyll b is yellow-green and assists in capturing light for photosynthesis. C - 3: Xanthophylls are yellow pigments that help in light absorption and provide protection. D - 1: Carotenoids are yellow to yellow-orange and play roles in light absorption and protection.
