(a) Describe the effect on chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light. (b) Identify an appropriate control that the researchers should use when they study the growth and photosynthetic ability of the plant with the mutant enzyme.
(c) Scientists claim that a plant that has more than one type of photosynthetic pigment has greater fitness than a plant that has only one type of photosynthetic pigment. Provide reasoning to justify this claim.
