One of the most common root systems is

• A. Xylem
• B. Fibrous
• C. Gymnosperm
• D. Filament

Answer: (B)

Understanding root system types helps explain how plants take up water and nutrients. A fibrous root system is made up of many thin roots that spread out from the base of the stem, forming a dense, shallow network. This pattern is one of the most common because it rapidly expands surface area near the soil where nutrients and moisture are often most available, and it provides good stabilization in a wide range of soils, especially in grasses and many monocots. It also tends to develop quickly from seeds or cuttings, aiding early establishment.

Xylem is tissue inside plants that moves water and minerals, not a root system. Gymnosperm is a plant group, not a root pattern. Filament is a slender part of a flower, not related to how roots form.
