An organelle is a specialized structure within a cell that performs a specific function. In this case, cellular respiration is the process of converting nutrients into energy, and the organelle responsible for this process is the mitochondrion. Option A, the chloroplast, is responsible for photosynthesis, not cellular respiration. Option B and D, the vacuole and ribosome, have different functions such as storage and protein synthesis, respectively. Therefore, C is the most suitable answer as it relates directly to the question.
