Final answer:
The light-dependent reactions of photosynthesis use water and produce oxygen.
Step-by-step explanation:
The statement is True. The light-dependent reactions of photosynthesis do indeed use water and produce oxygen. These reactions take place in the thylakoid membranes of the chloroplasts and are driven by light energy. The water molecules are split, releasing oxygen gas as a byproduct. The energy captured during these reactions is used to produce ATP and NADPH, which are then used in the light-independent reactions to produce carbohydrates.
