Intercalary meristem is present at the base of

Options

A. intermodes in grasses
B. leaves in pinus
C. nodes in mentha
D. all of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Intercalary Meristem**: Intercalary meristem is a type of meristematic tissue that is responsible for the growth of plants. It is located between mature tissues, specifically at the base of leaves and internodes.

2. **Identifying Locations**: The question asks where intercalary meristem is present. The options provided are:
- A) Internodes in grasses
- B) Leaves in Pinus
- C) Nodes in Mentha
- D) All of the above

3. **Analyzing Each Option**:
- **Option A (Internodes in grasses)**: Intercalary meristem is indeed found at the internodes of grasses, which allows for the elongation of the stem.
- **Option B (Leaves in Pinus)**: While Pinus (a type of conifer) does have meristematic tissue, intercalary meristem is not typically found in the leaves of Pinus. This option is not correct.
- **Option C (Nodes in Mentha)**: Nodes are regions where leaves are attached to the stem. Intercalary meristem is not specifically located at the nodes but can be involved in growth near them. This option is somewhat misleading.
- **Option D (All of the above)**: Since option B is incorrect, this option cannot be true.

4. **Conclusion**: The best answer based on the analysis is **A) Internodes in grasses**, as this is the primary location where intercalary meristem is found.

**Final Answer**: A) Internodes in grasses
