All of the following are secondary meristems except

Options

A. Intercalary meristems
B. Lateral meristems
C. Inter Fascicular cambium
D. Cork cambium

Answer

To solve the question "All of the following are secondary meristems except," we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Meristems**:
- Meristems are classified into two main categories: primary meristems and secondary meristems.
- Primary meristems are responsible for the elongation of the plant, while secondary meristems contribute to the increase in girth or thickness.

2. **Identify Primary Meristems**:
- The primary meristems include:
- **Apical Meristem**: Located at the tips of roots and shoots (root apical meristem and shoot apical meristem).
- **Intercalary Meristem**: Found at the base of leaves or internodes, contributing to the growth of the plant.

3. **Identify Secondary Meristems**:
- Secondary meristems include:
- **Vascular Cambium**: Involved in the formation of secondary vascular tissues.
- **Cork Cambium**: Responsible for the production of cork, which is part of the bark.

4. **Analyze the Given Options**:
- The question asks to identify which option is NOT a secondary meristem.
- The options typically include intercalary meristem, vascular cambium, cork cambium, and possibly another type of meristem.

5. **Determine the Correct Answer**:
- Among the options, intercalary meristem is a primary meristem, while vascular cambium and cork cambium are secondary meristems.
- Therefore, the correct answer is **intercalary meristem**.

### Final Answer:
The correct answer is **intercalary meristem** as it is the only option that is not a secondary meristem.
