Question 1 Read each question carefully. Write your response in the space provided for each part of each question. Answers must be written out in paragraph form. Outlines, bulleted lists, or diagrams alone are not acceptable and will not be scored. The chloroplasts of flowering land plants typically contain at least two photosynthetic pigments, chlorophyll a and chlorophyll b, that differ in the wavelengths of light they absorb. The synthesis of chlorophyll pigments from precursor molecules is a process that involves many sequential enzyme-catalyzed steps. Researchers studied the growth and photosynthetic ability of a plant that contained a mutant form of one of the enzymes required for chlorophyll biosynthesis. (a) Describe the effect on chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light. 0 / 10000 Word Limit Question 2 (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. 0 / 10000 Word Limit Question 3 (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.
