Benzoquinones occur in fungi and higher plants as yellow, orange, red, or violet pigments. Yellow coenzyme Q variants (ubiquinones) and plastoquinones are found in most plants. Because of their low tissue levels, they do not affect plant color.
Plants use energy from the sun in tiny energy factories called chloroplasts. The green color of leaves is attributable largely to these chloroplasts because they contain chlorophyll for photosynthesis.
