Plant themselves have a green color pigment in their leaves called chlorophyll which absorbs visible light.
Pigments absorb mostly the red and blue color light and reflect green light. This the reason why plants appear green to us and least likely to make food. Most of the autotrophs contain this green pigment.
Sulfa drugs, such as antibiotics that contain sulfonamides. Example: Some combination drugs such as Sulfamethoxazole-trimethoprim (Septra, Bactrim) and Erythromycin-sulfisoxazole contain sulfonamides. <span>
