The woody axis of flowering plants is produced by

Options

A. Apical meristem
B. Primary meristem
C. Intercalary meristem
D. Secondary meristem

Answer

To solve the question "The woody axis of flowering plants is produced by," we need to understand the different types of meristematic tissues and their roles in plant growth.

### Step-by-Step Solution:

1. **Understanding Meristematic Tissues**:
- Meristematic tissues are regions in plants where cells are actively dividing. These tissues are responsible for growth in plants.

2. **Types of Meristematic Tissues**:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for the increase in height.
- **Intercalary Meristem**: Found at the nodes and base of leaves, helps in the elongation of stems and leaves.
- **Primary Meristem**: Forms during the early stages of plant development, contributing to primary growth.
- **Secondary Meristem**: Also known as lateral meristem, it is responsible for secondary growth, which increases the thickness or girth of the plant.

3. **Focus on Secondary Meristem**:
- The secondary meristem includes tissues like vascular cambium and cork cambium. These tissues are crucial for the development of woody structures in plants.
- Secondary growth is what leads to the formation of wood in flowering plants.

4. **Conclusion**:
- Since the question specifically asks about the production of the woody axis, the correct answer is the **secondary meristem**.

### Final Answer:
The woody axis of flowering plants is produced by the **secondary meristem**.
