Intercalary meristem leads in

Options

A. secondary growth
B. primary growth
C. apical growth
D. secondary thickening

Answer

### Step-by-Step Solution:

1. **Understanding Intercalary Meristem**:
- Intercalary meristem is a type of meristematic tissue found in certain plants, particularly in monocots like grasses. It is located between mature tissues, typically at the base of leaves or internodes.

2. **Identifying the Function of Intercalary Meristem**:
- The primary function of intercalary meristem is to facilitate growth in length. This is particularly important for plants that experience grazing or cutting, as it allows them to regrow quickly.

3. **Differentiating Types of Growth**:
- **Primary Growth**: This refers to the increase in length of the plant due to the activity of apical meristems at the tips of roots and shoots.
- **Secondary Growth**: This involves the increase in thickness or girth of the plant, primarily due to the activity of lateral meristems (cambium).
- **Apical Growth**: This is a term often used interchangeably with primary growth, as it also refers to growth at the tips of roots and shoots.
- **Secondary Thickening**: This is a process associated with secondary growth, where new tissues are formed to increase the thickness of stems and roots.

4. **Conclusion**:
- Since intercalary meristem is responsible for primary growth by allowing elongation of the plant, the correct answer to the question "Intercalary meristem leads in" is **primary growth**.

### Final Answer:
Intercalary meristem leads in **primary growth**.
