The two most common root systems are taproot and

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

Answer: (B)

Plants have two main root system patterns that determine how they anchor themselves and take up water and nutrients: a vertical central root that grows downward (the taproot) and a network of many thin roots spreading out near the soil surface (the fibrous system). The fibrous root system is the other very common form alongside the taproot, especially in grasses and many annuals. Its dense mat of fine roots near the surface lets plants quickly absorb water and nutrients from upper soil layers and provides good soil stabilization in shallow soils. In contrast, a taproot produces a strong downward-growing main root with smaller lateral roots, giving deep anchorage and, in some species, carbohydrate storage. The other terms refer to different ideas (adventitious roots can arise from non-root tissue, and propagating relates to reproduction), so they don’t describe a root-pattern type.
