3.2: Roots
Roots are plant organs that are usually found underground. They not only anchor the plant, but also transport water, minerals, and sugars. In many plants, carbohydrates are stored in the roots so they can be used when needed. Roots can be very deep, and spread out very far. Some roots are as deep as the tree is high. Roots can also spread far beyond the canopy of the tree. However, being underground, they are often gone unnoticed.
