Chlorophyll a shows high absorption in the blue and red regions but reflects green light. Why does the action spectrum still show some photosynthesis in the green region?
Q1. Chlorophyll a shows high absorption in the blue and red regions but reflects green light. Why does the action spectrum still show some photosynthesis in the green region?
Answer: Presence of carotenoids
Explanation: Accessory pigments like carotenoids absorb wavelengths that chlorophyll a cannot, broadening the action spectrum. Chlorophyll b also reflects green light.
