Textbook Question
Chapter 7, Problem 3AC
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? Explain.

Students have asked these similar questions
Suppose that the whole plant doesn’t have green parts, can it still perform photosynthesis? Why or why not?
Provide interpretation on the chromatography of plant pigments
In photosynthesis, contrast the light reactions with the light independent reactions, in terms of goals, inputs, and outputs of each. Spatially where do they take place (which parts of the chloroplast)? (Optional, for further discussion: Could there be light reactions without light-independent reactions, or visa-versa?)
If you landed on a planet where all of the plants had purple leaves, what wavelengths of light would you expect to be least effective for photosynthesis? explain your reasoning.
