Intercalary meristem is related to all, except

Options

A. Present between permanent cells
B. Primary meristem
C. Increasing the grith of axis
D. Regenerates part of grasses removed by grazing herbivores.

Answer

### Step-by-Step Solution:

1. **Understand the Concept of Meristem**:
- Meristems are regions in plants consisting of undifferentiated cells that can divide and differentiate into various types of cells. They are responsible for growth in plants.

2. **Identify the Types of Meristem**:
- There are three main types of meristems:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for primary growth (length).
- **Lateral Meristem**: Found along the sides of stems and roots, responsible for secondary growth (girth).
- **Intercalary Meristem**: Located between the nodes (internodes) of stems, particularly in monocots, and is responsible for the elongation of internodes.

3. **Focus on Intercalary Meristem**:
- Intercalary meristem is specifically found at the base of leaves and between internodes. It plays a crucial role in the elongation of the stem and helps in regrowth after grazing.

4. **Evaluate the Options**:
- **Option A**: Present between permanent cells - This is true, as intercalary meristem is found between differentiated cells.
- **Option B**: Primary meristem - This is also true, as intercalary meristem is classified as a type of primary meristem.
- **Option C**: Increasing the girth of the axis - This is false. Intercalary meristem does not contribute to the girth (thickness) of the plant; it is involved in lengthening.
- **Option D**: Regenerates part of grasses removed by grazing herbivores - This is true, as intercalary meristem allows for regrowth in grasses.

5. **Conclusion**:
- The option that is not related to intercalary meristem is **Option C: increasing the girth of the axis**.

### Final Answer:
Intercalary meristem is related to all, except **increasing the girth of the axis**.
