Roots developed from parts of the plant other than radicle are called

Options

A. Taproots
B. Fibrous roots
C. Adventitious roots
D. Nodular roots

Answer

To solve the question "Roots developed from parts of the plant other than radicle are called," we need to analyze the options provided and understand the definitions of different types of roots.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Radicle**: This is the part of a seed that develops into the primary root. Roots that develop from the radicle are called primary roots.

2. **Analyze the Options**:
- **Option 1: Taproot**:
- Taproots arise from the radicle. They are typically found in dicot plants. Since the question specifies roots that develop from parts other than the radicle, this option is incorrect.

- **Option 2: Fibrous Root**:
- Fibrous roots also arise from the radicle, specifically in monocot plants. Therefore, this option is also incorrect for the same reason as the taproot.

- **Option 3: Adventitious Root**:
- Adventitious roots are those that develop from parts of the plant other than the radicle, such as stems or leaves. This fits the criteria of the question, making this option correct.

- **Option 4: Nodular Root**:
- Nodular roots are specialized roots that form nodules, commonly seen in leguminous plants for nitrogen fixation. These roots also do not arise from the radicle, but they are a specific type of root and not the general term for roots arising from other parts. However, they are not the best answer to the question.

3. **Conclusion**:
- The correct answer is **Option 3: Adventitious Root**. These roots develop from parts of the plant other than the radicle.

### Final Answer:
Roots developed from parts of the plant other than radicle are called **Adventitious Roots**.
