Unseen and buried beneath the soil, plant roots perform functions that are necessary to a plant's life. The roots collect water and nutrients for the plant and secure it to the soil. Two basic types of root systems exist. One type is the taproot, which grows vertically and has lateral branches. The other type has fibrous, branching roots that make a network close to the soil surface. Some plants have either a taproot or fibrous roots, and other plants combine the two systems.
