Intercalary meristems found in

Options

A. Root
B. Stem tip
C. Petiole and internodes
D. Latex

Answer

### Step-by-Step Solution:

1. **Understanding Intercalary Meristems**:
- Intercalary meristems are a type of meristematic tissue that is responsible for the elongation and growth of certain parts of the plant, specifically at the base of stem nodes and leaf internodes.

2. **Location of Intercalary Meristems**:
- These meristems are primarily found in monocots, particularly at the base of leaf primordia and internodes. They play a crucial role in the growth of grasses and other similar plants.

3. **Differentiating Types of Meristems**:
- It's important to differentiate intercalary meristems from other types of meristems:
- **Apical Meristems** are located at the tips of roots and shoots and are responsible for primary growth.
- **Lateral Meristems** are involved in secondary growth, increasing the thickness of stems and roots.
- Since intercalary meristems are not located at the tips, they can be distinguished from apical meristems.

4. **Function of Intercalary Meristems**:
- The main function of intercalary meristems is to facilitate the longitudinal growth of stems and leaves. In monocots, they allow for the extension of petioles, which helps leaves rise above water surfaces.

5. **Identifying the Correct Answer**:
- Given the options (roots, stem tip, petiole, and internodes), we can eliminate roots and stem tips as they are associated with apical meristems.
- The correct answer is therefore petiole and internodes, where intercalary meristems are found.

### Final Answer:
Intercalary meristems are found in the petiole and internodes of plants, particularly in monocots.
