The term for two common root systems is

• A. Adventitious and Tap
• B. Primary and Secondary
• C. Fibrous and Tap
• D. Taproot and Fibrous

Answer: (C)

Two common root systems are fibrous and taproot. A fibrous root system has many slender roots that spread out near the soil surface, forming a dense network that quickly absorbs water and nutrients and helps hold soil in place—typical of grasses and many monocots. A taproot system features one dominant thick root that grows downward with smaller lateral roots branching off, allowing deeper soil penetration and storage of nutrients—common in many dicots like carrots. This pairing directly names the two principal root system types, making it the best answer. The other options mix terms that don’t describe the two main root system categories in the same way. Adventitious refers to roots that arise from non-root tissue, primary and secondary describe root development stages rather than distinct systems, and combining fibrous with taproot is the same idea as the correct pair, just in a different order.
