The intercalary meristem is present in
(a) Mint
(b) Grasses
(c) Bamboo
(d) All of these

Options

A. Mint
B. Grasses
C. Bamboo
D. All of these

Answer

To determine where intercalary meristem is present, let's analyze each option step by step:

1. **Understanding Intercalary Meristem**:
- Intercalary meristems are regions of growth found at the base of internodes (the segments between the nodes) in plants.
- Their primary function is to facilitate elongation and growth, particularly in the stems and leaves.

2. **Analyzing the Options**:
- **Option (a) Mint**: Mint is a dicot plant. While it has meristematic tissues, intercalary meristems are not typically prominent in mint.
- **Option (b) Grasses**: Grasses are monocots and are well-known for having intercalary meristems at the base of their internodes, which allows for rapid growth and elongation.
- **Option (c) Bamboo**: Bamboo is also a type of grass (monocot) and possesses intercalary meristems, contributing to its rapid growth.
- **Option (d) All of these**: This option suggests that intercalary meristems are present in all the listed plants.

3. **Conclusion**:
- After analyzing each option, we find that intercalary meristems are primarily present in grasses and bamboo, but not in mint. Therefore, the correct answer is **(b) Grasses**.

### Final Answer: (b) Grasses
