Final answer:
In biology, potatoes develop through a photoperiodic response from the tips of underground stems. Stores should cut potatoes in advance based on their schedule and demand.
Step-by-step explanation:
The question pertains to the biological process by which potatoes develop from the tips of short underground stems, also known as stolons. This process is influenced by a photoperiodic response, which is triggered by environmental cues such as shorter days.
Therefore, for a store preparing for morning prep, it would be ideal to start cutting the potatoes well in advance to ensure they are ready for use when required. However, the exact timing would depend on the store's operational schedule and the volume of potatoes needed for the day's business.
