No. Even though the part of the potato we eat grows in the ground, it is not the root of the plant.

potatoes are stems

It is the underground part of the stem that has thickened. This part of the stem is called a tuber.

Tubers thicken and grow big because they store the food supply for the leafy part of the plant above ground.
