Correct Answer: C
Explanation:
Chloroplasts in green plants have a permeable outer membrane and an impermeable inner membrane that encloses the stroma which corresponds to the matrix in mitochondria. In addition there are interconnected membranous sacs called thylakoids. There are two photosystems named PSI and PSII, in order of their discovery but PSII occurs first in the photosynthetic process. These are connected by a complex called cytochrome bf. In the overall process electrons are extracted from water, liberating oxygen. The energy for this comes indirectly from light and transmitted by the three complexes to finally reduce NADP, ATP being generated on the way by the cytochrome bf complex. The products from these light-dependent reactions, NADPH and ATP are then used in the light-independent Calvin cycle to synthesize carbohydrates from CO2 and water.
