Cells of permanent tissues are specialised -

Options

A. Functionally
B. Only structurally
C. Both structurally and functionally
D. For mitosis

Answer

**Step-by-Step Solution:**

1. **Understanding Permanent Tissues**: Permanent tissues in plants are those that have differentiated and are no longer capable of division. They are specialized for specific functions and structures.

2. **Identifying Specialization**: The cells of permanent tissues can be specialized in two main ways:
- **Functionally**: This means that the cells are adapted to perform specific functions, such as water conduction in xylem cells.
- **Structurally**: This refers to the physical characteristics of the cells, which can be adapted to their roles, such as the isodimetric shape of parenchyma cells.

3. **Evaluating the Options**:
- **Option 1 (Functionally)**: This is correct as permanent tissues like xylem are specialized for specific functions such as water conduction.
- **Option 2 (Only Structurally)**: This is also correct because cells like parenchyma have specific structural adaptations.
- **Option 3 (Both Structurally and Functionally)**: This is the most comprehensive answer, as it acknowledges that permanent tissues are specialized in both aspects.
- **Option 4 (For Mitosis)**: This is incorrect because mitosis is a characteristic of meristematic tissues, not permanent tissues.

4. **Conclusion**: The most accurate answer to the question is that cells of permanent tissues are specialized both structurally and functionally.

**Final Answer**: Option 3 - Both structurally and functionally.
