A secondary meristematic tissue can develop due to the resumption of power of division in

Options

A. parenchyma and sclerenchyma
B. parenchyma and collenchyma
C. Collenchyma and sclerenchyma
D. Collenchyma and tracheids.

Answer

To answer the question "A secondary meristematic tissue can develop due to the resumption of power of division in," we need to analyze the options provided and understand the characteristics of the tissues involved.

### Step-by-step Solution:

1. **Understanding Meristematic Tissue**:
- Meristematic tissues are composed of undifferentiated cells that have the ability to divide and differentiate into various types of cells. They are found in specific regions of the plant, such as the tips of roots and shoots, and in lateral meristems like the vascular cambium and cork cambium.

2. **Identifying Permanent Tissues**:
- Permanent tissues are formed from meristematic tissues that have lost their ability to divide. They are classified into simple permanent tissues (parenchyma, collenchyma, and sclerenchyma) and complex permanent tissues.

3. **Characteristics of the Tissues**:
- **Parenchyma**: Living cells with the ability to divide and can revert to a meristematic state under certain conditions.
- **Collenchyma**: Also living cells that provide support and can similarly revert to a meristematic state.
- **Sclerenchyma**: Composed of dead cells that do not have the ability to divide or revert to a meristematic state.
- **Tracheids**: A type of sclerenchyma found in xylem, also incapable of division.

4. **Evaluating the Options**:
- **Parenchyma and Sclerenchyma**: Incorrect, as sclerenchyma cannot divide.
- **Parenchyma and Collenchyma**: Correct, as both can resume division.
- **Collenchyma and Sclerenchyma**: Incorrect, as sclerenchyma cannot divide.
- **Collenchyma and Tracheids**: Incorrect, as tracheids (sclerenchyma) cannot divide.

5. **Conclusion**:
- The only viable option is **Parenchyma and Collenchyma**, as both tissues can resume their meristematic activity and contribute to the formation of secondary meristematic tissues.

### Final Answer:
A secondary meristematic tissue can develop due to the resumption of power of division in **Parenchyma and Collenchyma**.
