Which root system is described as having a main tap root, with root numbers arising from the base of the stem?

• A. Tap Root System
• B. Fibrous Root System
• C. Adventitious Roots
• D. Prop Roots

Answer: (B)

Fibrous root systems are defined by many thin roots emerging from the base of the stem, forming a dense, shallow network with no single dominant root. This contrasts with a tap root system, where a single main root grows downward from the seed’s radicle and lateral roots branch off from that main root. Adventitious roots are roots that arise from non-root tissues (such as stems or leaves) and can be part of either system, while prop roots are specialized adventitious roots that provide extra support. The description given—numerous roots arising from the stem base—best matches a fibrous root system, which is why that option fits.
