Hint: Potato tuber is a modified or edible part of that section of the plant that bears branches, leaves, flowers, and fruits. This part is modified to perform different functions and in the case of potatoes, it is modified to be underground and to store food in them.

Complete answer: In some plant species present tuber, which is an enlarged structure used as an organ for the storage of food or nutrients. These are the modifications of the stem. They are used as a means of asexual reproduction. Underground modified stems such as bulbs, suckers, tubers, etc grow in new plants and help in vegetative reproduction. In potatoes, tubers are modified underground stem branches having several buds. Each eye present in the potato tuber is a bud and it grows into a new potato plant when planted with a portion of the swollen tuber. The tuber is developed in one growing season and they are used as a means of propagation to penetrate the plant. These tubers are variable in shapes having four types which are- round, compressed, long, and oval. As a food, these tubers can be baked, fried, boiled, mashed, or made into flour. They are a rich source of starch. Also, Bulbs are present in onions, garlic, etc. Roots are modified into tubers in sweet-potato, Tapioca, etc. Stolon is the creeping stems.
