Permanent tissue consists of cells having no power of cell division. Such tissues are formed by -

Options

A. Primary meristem
B. Cork cambium
C. Fascicular and interfascicular cambium
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Permanent Tissue**: Permanent tissues in plants are composed of cells that have lost the ability to divide. This means that once these cells have differentiated, they take on specific functions and do not undergo further division.

2. **Formation of Permanent Tissue**: Permanent tissues are formed from meristematic tissues, which are regions of actively dividing cells. When meristematic cells differentiate and mature, they become permanent tissues.

3. **Types of Permanent Tissues**: Permanent tissues can be classified into two main categories: simple permanent tissues and complex permanent tissues. Simple tissues consist of one type of cell, while complex tissues are made up of different types of cells working together.

4. **Examples of Permanent Tissues**:
- **Simple Permanent Tissues**: Parenchyma, Collenchyma, and Sclerenchyma.
- **Complex Permanent Tissues**: Xylem and Phloem.

5. **Conclusion**: Therefore, permanent tissues are formed by the differentiation of meristematic tissues, which lose their ability to divide and specialize in function.
