These cells help in increasing the length of the plant by undergoing cell division

Options

A. xylem
B. phloem
C. meristematic cells
D. sclerenchyma

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which type of cells are responsible for increasing the length of the plant through cell division.

2. **Identifying the Options**: The options provided are:
- Xylem
- Phloem
- Meristematic cells
- Sclerenchyma

3. **Analyzing Each Option**:
- **Xylem**: This is a type of vascular tissue responsible for the transport of water and minerals from the roots to other parts of the plant. It does not play a role in increasing the length of the plant.
- **Phloem**: This is another type of vascular tissue that transports nutrients, particularly sugars, throughout the plant. Like xylem, it does not contribute to the increase in length.
- **Sclerenchyma**: This tissue provides structural support to the plant and consists of dead cells. It does not undergo cell division and thus does not contribute to growth in length.
- **Meristematic Cells**: These are undifferentiated cells found in meristematic tissue. They have the ability to divide and can differentiate into various types of plant tissues. They are primarily responsible for the growth in length of the plant.

4. **Conclusion**: The correct answer is **Meristematic cells**. These cells are crucial for the growth of the plant as they undergo cell division and help in elongating the plant.
