In botany, a fusiform root is a type of root that is thickened in the middle and tapers towards both the ends, resembling a spindle shape. It is a specific kind of tap root.
The fusiform root structure is most commonly associated with the carrot. Let's explore why:
- Carrot: The carrot is a classic example of a fusiform root. It exhibits the spindle shape with a wider middle that tapers at both ends.
- Radish: Radish roots are typically napiform (turnip-like), but can sometimes be conical or cylindrical, not accurately fusiform.
- Turnip: Turnip roots are napiform, swollen like a ball, with abrupt tapering, hence not fusiform.
- Sweet potato: Sweet potatoes have tuberous roots, which are not classified as fusiform; they are irregularly shaped due to storage organ formations.
Therefore, among the given options, the correct answer for a plant with a fusiform root is the Carrot.
