Anomalous secondary growth found in dicot root of

Options

A. Raphanus
B. Dacus
C. Beta
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Anomalous Secondary Growth**:
- Anomalous secondary growth refers to an irregular or abnormal pattern of growth in the vascular tissues of plants. This type of growth is characterized by the presence of secondary xylem and phloem in unusual arrangements.

2. **Identifying the Context**:
- The question specifically asks about anomalous secondary growth in the dicot root. Dicotyledons (dicots) are a group of flowering plants that typically exhibit a certain pattern of growth, but some species show deviations from this norm.

3. **Examples of Dicot Roots with Anomalous Secondary Growth**:
- The options provided are Raffinus, Dacus, and Beta. These are all examples of dicot plants.
- Raffinus (commonly known as turnip), Dacus (commonly known as carrot), and Beta (commonly known as beetroot) are all known to exhibit anomalous secondary growth in their roots.

4. **Analyzing the Options**:
- All three options (Raffinus, Dacus, and Beta) are known to demonstrate this type of growth.
- Therefore, the correct answer to the question is that anomalous secondary growth can be found in all of these dicot roots.

5. **Conclusion**:
- The final answer is that anomalous secondary growth is found in the dicot roots of Raffinus, Dacus, and Beta, making the correct option number four (all of them).
