Why is the structure of a leaf cells (potato tuber) is unable to perform the function of the tuber cells efficiently?

The structure of leaf cells, primarily designed for photosynthesis, contains chloroplasts and a large surface area to capture sunlight, which is not required in potato tuber cells. Potato tuber cells, on the other hand, are specialized for storage, featuring a dense cytoplasm and large vacuoles filled with starch. This specialization allows tuber cells to efficiently store energy, while leaf cells lack the necessary adaptations for storage functions. Consequently, the structural differences limit the efficiency of leaf cells in performing the storage functions essential to tubers.
