Which root system is described as being widespread with many fine roots near the soil surface?

• A. Taproot
• B. Fibrous
• C. Taproot with deep anchor
• D. Carrot-like

Answer: (B)

A fibrous root system is made up of many slender roots that spread out widely near the soil surface, forming a dense network rather than one central dominant root. This arrangement provides a large surface area right at the top of the soil, so plants can quickly absorb water and nutrients from the upper layer and helps hold loose soil in place, reducing erosion. The description of being widespread with lots of fine roots near the surface fits this pattern, which is common in grasses and many shallow-rooted plants. In contrast, a taproot system features a single, thicker primary root that grows downward to form a deep anchor, with fewer surface roots—think of carrots or dandelions. A taproot with a deep anchor emphasizes that downward growth, not widespread surface rooting. A carrot-like reference is a classic example of that deep, dominant root structure.
