What are the two most common root systems?

• A. Fibrous and tap
• B. Hairs and filaments
• C. Sepals and gymnosperms
• D. Xylem and phloem

Answer: (A)

Root system type describes how a plant’s roots are organized. The two most common forms are fibrous and taproot.

Fibrous roots form a dense mat of many thin roots that spread out near the soil surface. This pattern is typical of grasses and other monocots and is great for quickly taking up surface moisture, providing good soil stabilization, and spreading outward to anchor shallow soils.

Taproot systems have one main thick root that grows downward with smaller lateral roots branching off. This arrangement is common in many dicots like carrots and dandelions, enabling deeper access to moisture and nutrients and often storing carbohydrates in the main root.

Understanding these types helps explain how plants interact with soil, how they should be watered, and how they withstand drought or support transplantation. The other options refer to plant parts or tissues—root hairs are tiny extensions on roots, xylem and phloem are tissues for transport, and sepals are floral parts—not root systems.
