Photosynthesis Redefined

Remember learning about the process of photosynthesis in first year biology? OK, neither do I. Nonetheless, from the little that I do recall, I remember that chlorophyll is responsible for converting sunlight into energy for plant survival. Well, it turns out that the chlorophyll pigments do not act alone. Researchers from the University of Toronto have found that Carotenoids, the same pigments which give orange color to carrots and red to tomatoes, are often found together in plants with chlorophyll pigments that harvest solar energy. Their main function is photoprotection when rays of light from the sun are the most intense. However, a new study published in Science this week shows how they capture blue/green light and pass the energy on to chlorophylls, which absorb red light.
