Which root system is described as a network of many fine roots that spread near the soil surface?

• A. Fibrous
• B. Taproot
• C. Storage
• D. Adventitious

Answer: (A)

The main idea here is distinguishing root system types by how they spread in the soil. A fibrous root system forms a dense network of many fine roots that spread out near the soil surface, rather than a single dominant root growing deep. This pattern is typical of grasses and many herbaceous plants and helps quickly absorb moisture and nutrients from the upper soil while also stabilizing the surface soil. In contrast, a taproot system features one main thick root that grows downward with smaller lateral roots branching off, reaching deeper into the soil. Storage roots are thickened to store carbohydrates, as seen in carrots or beets. Adventitious roots arise from non-root tissues like stems or leaves and can provide extra support or nutrients.
