The Advantages of the Fibrous Root & Taproot Systems. Fibrous roots branch from the plant's base, and taproots go straight down. 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.
Fibrous Root System: Characterized by having a mass of similarly sized roots. In this case the radicle from a germinating seed is short lived and is replaced by adventitious roots. Adventitious roots are roots that form on plant organs other than roots. Most monocots have fibrous root systems. Some fibrous roots are used as storage; for example sweet potatoes form on fibrous roots. Plants with fibrous roots systems are excellent for erosion control, because the mass of roots cling to soil particles. Top of Page. Root Structures and Their Functions: Root Tip: the end 1 cm of a root contains young tissues that are divided into the root cap, quiescent center, and the subapical region. Root Cap: root tips are
