Which of the following statements about carotenoids in green plants is correct? A - Scottish Highers Biology - Question 19 - 2022

Carotenoids are important pigments found in plants that play a crucial role in photosynthesis. They help broaden the spectrum of light absorbed by plants, enabling them to capture additional energy from sunlight. Unlike chlorophyll, which mainly absorbs blue and red light, carotenoids can absorb green, yellow, and other wavelengths of light that chlorophyll does not utilize efficiently.

By extending the range of wavelengths, carotenoids facilitate the transfer of energy to chlorophyll, enhancing the overall efficiency of photosynthesis. This allows the plant to optimize energy capture from the sun, thereby supporting growth and vitality.
