The infrascicular cambium

Options

A. Is a simple permanent tissues
B. Is a meristematic tissue
C. Is a complex permanent tissues
D. Is secondary meristern

Answer

### Step-by-Step Solution:

1. **Understanding Infrascicular Cambium**: The infrascicular cambium is a type of cambium found in the vascular bundles of plants. It is located between the xylem and phloem tissues.

2. **Classification of Tissues**: Tissues in plants can be classified into three main categories:
- Simple permanent tissues
- Complex permanent tissues
- Meristematic tissues

3. **Identifying the Type of Cambium**: The infrascicular cambium is specifically a type of cambium that is involved in the growth of the plant. It is derived from the procambium, which is a primary meristem.

4. **Location of Infrascicular Cambium**: The infrascicular cambium is situated within the open vascular bundles, which means it is found between the xylem and phloem tissues.

5. **Function During Growth**: The infrascicular cambium becomes active during the secondary growth of plants, contributing to the increase in girth.

6. **Evaluating the Options**:
- **Simple Permanent Tissue**: Incorrect, as the infrascicular cambium is not a permanent tissue.
- **Meristematic Tissue**: Correct, as it is a type of meristematic tissue that can divide and contribute to growth.
- **Complex Permanent Tissue**: Incorrect, as it does not fit this classification.
- **Secondary Meristem**: Incorrect, as it is a primary meristem derived from procambium.

7. **Conclusion**: The correct classification of the infrascicular cambium is that it is a **meristematic tissue**.
