A plant is exposed to extremely high-intensity light that could potentially damage its photosynthetic apparatus. Which pigments provide a protective function against photo-oxidation?
Q1. A plant is exposed to extremely high-intensity light that could potentially damage its photosynthetic apparatus. Which pigments provide a protective function against photo-oxidation?
Answer: Carotenoids
Explanation: Carotenoids protect chlorophyll from intense light; chlorophyll b is an accessory pigment but its primary role is broadening the absorption spectrum.
