What part of a potato plant stores most the food made by its leaves?

The part of a potato plant that stores most of the food made by its leaves is the tuber.

Here's why:

* Tubers are modified stems: They are underground storage organs that store starch and other nutrients produced by the leaves through photosynthesis.

* Leaves are the food factories: They use sunlight, water, and carbon dioxide to produce sugars (food).

* The plant transports food: The sugars are transported through the plant's vascular system (xylem and phloem) to the tubers for storage.

So, the tubers act like a pantry for the potato plant, providing it with energy and nutrients for growth and reproduction when needed.
