Find odd one w.r.t. tissues developed by the process of redifferentiation

Options

A. Secondary cortex
B. Secondary xylem
C. Phellem
D. Phellogen

Answer

To find the odd one out with respect to the tissues developed by the process of redifferentiation, we need to analyze the options given: secondary cortex, secondary xylem, phloem, and phelogen.

### Step-by-Step Solution:

1. **Understanding Redifferentiation**:
- Redifferentiation is the process where mature tissues regain the ability to divide and form new tissues. This typically occurs after dedifferentiation, where mature cells lose their specialized functions and revert to a more meristematic state.

2. **Identifying the Tissues**:
- **Secondary Cortex**: This tissue is formed from the cambium and can undergo redifferentiation.
- **Secondary Xylem**: This is also formed from the vascular cambium and can undergo redifferentiation.
- **Phloem**: Like secondary xylem, phloem is formed from the cambium and can undergo redifferentiation.
- **Phelogen**: This is a tissue that forms the cork cambium, which does not typically undergo redifferentiation.

3. **Analyzing Each Tissue**:
- Secondary cortex, secondary xylem, and phloem can all undergo redifferentiation after dedifferentiation.
- Phelogen, however, does not typically show the ability to undergo redifferentiation in the same way as the other three tissues.

4. **Conclusion**:
- Therefore, the odd one out with respect to the tissues developed by the process of redifferentiation is **phelogen**.

### Final Answer:
**Phelogen** is the odd one out with respect to the tissues developed by the process of redifferentiation.
