Tubers can take many different shapes and sizes, and can be found in a wide variety of plant species. Some of the most well-known tuber-producing plants include potatoes, sweet potatoes, yams, and cassava. These plants are important sources of food for humans and animals, and are often cultivated on a large scale for commercial purposes.

Tubers are typically harvested from the soil once they have matured and reached their full size. They can then be stored for long periods of time without spoiling, making them an important source of food during times of scarcity. Many different cultures have developed unique recipes and cooking techniques for preparing tubers, and they are used in a wide variety of dishes around the world.
