What do you call vegetables like potato?

Here's why:

* Tubers are underground stems that store food. They are typically swollen and have buds (eyes) that can sprout new plants.

* Roots are the underground parts of a plant that absorb water and nutrients. They are not typically edible.

While potatoes are often referred to as vegetables, they are technically starchy root vegetables. This is because they are edible underground stems that are high in starch.
