TORONTO, ON – Pigments found in plants and purple bacteria employed
to provide protection from sun damage do more than just that.
Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis.

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.
