Potato is one of the most widely used edible plants. The edible part of the potato is called a tuber. The tubers of a potato plant grow underground. Other parts of the potato plant are inedible.

Potatoes come in many different colours. The most popular types of potato are usually yellow or brown in colour, but there are also red and even black varieties. Potatoes contain a lot of starch, as well as some protein and vitamin C. 

Potatoes can be eaten in various foods: they can be boiled, they can be made into potato mash, or they can be fried. French fries and potato chips are popular potato-based foods. Potatoes can also be ground to make starch, which is a type of potato flour used in cooking..
