Fusiform. Conical and napiform root are the modification of what type of root :-

Options

A. Adventitious root
B. Fibrous root
C. Tap root
D. Fasciculated root

Answer

To determine the type of root that fusiform, conical, and napiform roots are modifications of, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Root Types**:
- Begin by identifying the different types of roots. The main types include:
- Adventitious roots
- Fibrous roots
- Tap roots
- Fasciculated roots

2. **Identify Modifications**:
- Recognize that fusiform, conical, and napiform roots are specific modifications of roots.
- Fusiform roots are wider in the middle and taper at both ends.
- Conical roots are widest at the top and taper downwards.
- Napiform roots are bulbous at the top and taper sharply at the bottom.

3. **Relate Modifications to Root Types**:
- Compare these modifications to the types of roots:
- Adventitious and fibrous roots generally do not exhibit these modifications.
- Fasciculated roots also do not show these characteristics.
- Tap roots, however, can exhibit these modifications.

4. **Conclusion**:
- Since fusiform, conical, and napiform roots are modifications that can be observed in tap roots, we conclude that the correct answer is **tap root**.

### Final Answer:
Fusiform, conical, and napiform roots are modifications of **tap roots**.
