Nodes and internodes are present in the

Options

A. Leaf apex
B. Fibrous root
C. Tap root
D. Stem

Answer

**Step-by-Step Solution:**

1. **Understanding Nodes and Internodes**:
- Nodes are specific points on a stem where leaves arise.
- Internodes are the segments of the stem between two nodes.

2. **Identifying the Structure**:
- In a plant, the stem is the main structure that supports leaves, flowers, and fruits.
- The nodes and internodes are integral parts of the stem.

3. **Analyzing the Options**:
- The question asks where nodes and internodes are present.
- We need to consider the options provided: stem, leaf apex, fibrous roots, and tap root.

4. **Eliminating Incorrect Options**:
- **Leaf Apex**: This is the tip of the leaf and does not contain nodes or internodes.
- **Fibrous Roots and Tap Root**: These are types of roots, and roots do not have nodes or internodes since leaves do not arise from roots.

5. **Conclusion**:
- Since nodes and internodes are features of the stem, the correct answer is that nodes and internodes are present in the **stem**.

**Final Answer**: Nodes and internodes are present in the **stem**.
