Dandelions are commonly identified by which root feature?

• A. Have a sturdy taproot
• B. Have a shallow fibrous root system
• C. Lack roots during drought
• D. Lack roots altogether

Answer: (A)

The feature being tested is the root system type that helps identify the plant. Dandelions are known for a sturdy taproot—a single thick main root that grows downward with smaller roots branching off. This deep, robust taproot stores nutrients, helps the plant survive mowing and drought, and makes it possible for the plant to regrow if the top is removed but the root remains.

The other options don’t fit because a shallow fibrous root system is not characteristic of dandelions; they rely on a deep taproot rather than a widespread surface-rooted network. Saying they lack roots during drought or lack roots altogether is incorrect, since the taproot remains and functions year-round, supporting the plant’s persistence.
