Growth of cell wall during cell elongation takes place by:-

Options

A. Apposition
B. Intussusception
C. Both A and B
D. Super position

Answer

To answer the question regarding how the growth of the cell wall during cell elongation takes place, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cell Wall Growth**:
- The cell wall is a rigid structure that surrounds the cell membrane in plant cells. During cell elongation, the cell wall must grow to accommodate the increasing size of the cell.

2. **Analyzing the Options**:
- **Option A: Opposition**: This option suggests that growth occurs by forming new layers on top of existing layers. This is incorrect because it does not accurately describe the mechanism of cell wall growth during elongation.

- **Option B: Inter Suspension**: This option indicates that growth occurs through the deposition of new material between the existing components of the cell wall. This is the correct mechanism, as it allows for the expansion of the cell wall while maintaining its integrity.

- **Option C: Both A and B**: This option cannot be correct since Option A is already deemed incorrect.

- **Option D: Superposition**: This option implies that growth occurs by stacking layers on top of each other, which is also incorrect for cell elongation.

3. **Conclusion**:
- Based on the analysis of the options, the correct answer is **Option B: Inter Suspension**. This reflects the process by which new materials are deposited between existing cell wall components, facilitating cell elongation.

### Final Answer:
The growth of the cell wall during cell elongation takes place by **Inter Suspension**.
