A napiform root shape is characteristic of which plant root type?

• A. Conical
• B. Fusiform
• C. Napiform
• D. Fibrous

Answer: (C)

Napiform describes a root that is swollen at the top and tapers into a long, slender tail, giving a turnip-like appearance. This distinctive bulging upper portion with a long taper defines the napiform root type, so the shape itself uniquely matches this category. By contrast, a conical root broadens near the crown and then smoothly tapers to a point; a fusiform root is thick in the middle and tapers toward both ends like a spindle; a fibrous root system lacks a single dominant taproot and forms many small roots. Recognizing the swollen-to-tail pattern is what ties the term napiform to its root type.
