Final answer:
The vacuole is the eukaryotic organelle correctly matched with its function of material storage. Thus, the option B is the correct answer.
Step-by-step explanation:
Among the options listed for matching eukaryotic organelles with their correct function, B. vacuole--storage of materials is the correctly matched pair. A vacuole principally serves as a storage area within a cell, and in plant cells, it can also contribute to the breakdown of macromolecules.
The flagellum's primary function is related to cell movement, not DNA exchange. Mitochondria are often referred to as the powerhouses of the cell because they generate ATP through cellular respiration, rather than performing protein synthesis. The glycocalyx is involved in cell recognition and protection; it is not a semipermeable membrane.
