Textbook Question
Chapter 7, Problem 4AC
Assume you want to add an accessory pigment to the photosystems of a plant chloroplast to help it photosynthesize more efficiently. What wavelengths of light would the new pigment absorb? Describe the color of your new pigment. Would this be a useful project for genetic engineers?
