The following question came from the Mastering Biology homework. A spaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. Plants will be grown to provide oxygen and to recycle carbon dioxide. Since the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed. Suppose a plant has a unique photosynthetic pigment and the leaves of this plant appear to be reddish yellow. What wavelengths of visible light are absorbed by this pigment?(a) blue and violet(b) green and red(c) red and yellow(d) green and yellow Explain why (a) is correct.  (Note: You must adequately explain/defend your answer to demonstrate that you truly understand the material to earn points.)
