Options

B. Carrot
C. Turnip
D. Sweet potato

Answer

To solve the question "Which of the following is an example of modified adventitious fasciculated root?", we need to analyze each of the options provided.

### Step 1: Understand the terms
- **Adventitious roots** are roots that grow from unusual places, such as stems or leaves, rather than from the primary root.
- **Fasciculated roots** are a type of adventitious root that grow in clusters or groups.
- **Modified roots** are roots that have adapted to perform functions other than the typical absorption of water and nutrients.

### Step 2: Analyze each option
1. **Asparagus**: This plant has adventitious fasciculated roots that are swollen and grow in clusters at the base of the stem. This fits the definition of modified adventitious fasciculated roots.

2. **Carrot**: This is a taproot, which is a primary root that grows deep into the soil. It is not an adventitious root, so it does not fit the criteria.

3. **Turnip**: Similar to the carrot, the turnip is also a taproot. It is not classified as an adventitious root, thus it does not meet the requirement.

4. **Sweet Potato**: The sweet potato has tuberous roots, which are modified adventitious roots but do not specifically fit the definition of fasciculated roots, as they do not grow in clusters.

### Step 3: Conclusion
Based on the analysis, the correct answer is **Asparagus**, as it is the only option that represents a modified adventitious fasciculated root.

### Final Answer:
**Asparagus** is an example of modified adventitious fasciculated root.
