Which of the following is an advantage of having two slightly different photosystems in the chloroplasts? A)Twice as many electrons can be excited by a given amount of light energy. B)Cells are able to use light energy at twice the maximum efficiency predicted for cells with a single photosystem. C)Cells are able to use both blue and green wavelengths of light for photosynthesis. D)Electrons can be extracted from water and used to reduce NADP⁺ to NADPH.

The presence of two photosystems in chloroplasts allows for the extraction of electrons from water, which are then used to reduce NADP+ to NADPH. This process is essential for the light-dependent reactions of photosynthesis, where photosystem II (PSII) extracts electrons from water, and photosystem I (PSI) facilitates their use in reducing NADP+ to NADPH.
