Cyclic electron flow may be photoprotective (protective to light-induced damage). Which of the following experiments could provide information on this phenomenon
A. Using mutated organisms that can grow but that cannot carry out cyclic flow of electrons and compare their abilities to photosynthesis in different light intensifies
B. Using plants that can carry out both linear and cyclic electron flow, or only one or another of three processes, and measuring their light absorbable
C. Using bacteria that have only cyclic flow and look for their frequency of mutation damage
D. Using bacteria with only cyclic flow and measuring the number and the types of photosynthetic pigments they have in their membranes
E. Using plants with only photosystem I operative and measure how much damage occurs at different wavelengths
Answer: A
