Radish has
(a) Fusiform root
(b) Napiform root
(c) Conical root
(d) Tuberous root

Options

A. Fusiform root
B. Napiform root
C. Conical root
D. Tuberous root

Answer

To determine the type of root that radish has, we will analyze the options provided:

1. **Understanding Root Modifications**: Roots can undergo various modifications based on their functions, particularly for food storage. The main types of modified tap roots include:
- Fusiform root
- Napiform root
- Conical root
- Tuberous root

2. **Analyzing Each Option**:
- **(a) Fusiform root**: This type of root is swollen in the middle and tapers at both ends. This description fits the structure of a radish root.
- **(b) Napiform root**: This type of root is bulbous and swollen at the top, resembling a turnip. This does not match the structure of radish.
- **(c) Conical root**: This root has a cone-like shape and is not swollen in the middle. This does not describe radish.
- **(d) Tuberous root**: These roots are swollen and can have multiple storage roots. This does not accurately represent the radish root either.

3. **Conclusion**: Since the radish root is swollen in the middle and tapers at both ends, it is classified as a **fusiform root**.

Thus, the correct answer is **(a) Fusiform root**.
