Final answer:
The mismatched pair is D. Centrosome/food storage. The centrosome is involved in cell division and microtubule organization, not food storage.
Step-by-step explanation:
In the context of a eukaryotic cell's structure and function, the mismatched pair is D. Centrosome/food storage. The centrosome is actually associated with the organization of microtubules and plays a crucial role in the process of cell division, particularly during the formation of the spindle apparatus. It is not involved in food storage. In contrast, the endoplasmic reticulum supports internal transport, the Golgi apparatus is involved in the secretion of substances, mitochondria are renowned for ATP production, and lysosomes contain digestive enzymes used for breaking down waste materials and cellular debris within the cell.
