Cell of maturation phase show

Options

A. Thickening of cell walls
B. Protoplasmic modification
C. Both (A) and (B)
D. None of these

Answer

To solve the question regarding the cells of the maturation phase, we will analyze the characteristics of cells in this phase step by step.

### Step-by-Step Solution:

1. **Understanding the Maturation Phase**:
- The maturation phase in plant cells is the stage where cells have completed their elongation and are now undergoing differentiation and maturation.

2. **Characteristics of Cells in the Maturation Phase**:
- **Cell Size**: Cells in the maturation phase attain their maximum size. This is due to the completion of cell elongation.
- **Cell Wall Thickness**: During this phase, the cell walls become thicker. This thickening is important for providing structural support and protection.
- **Protoplasmic Modifications**: Cells also undergo various modifications in their protoplasm, which allows them to differentiate into various types of tissues (simple and complex) that perform specific functions.

3. **Evaluating the Options**:
- **Option A: Thickness of the cell wall**: This is true as cells in the maturation phase do exhibit increased wall thickness.
- **Option B: Protoplasmic modification**: This is also true as cells differentiate and modify their protoplasm to form different tissues.
- **Option C: Both A and B**: Since both statements A and B are correct, this option is also correct.
- **Option D: None of these**: This option is incorrect as we have established that A and B are true.

4. **Conclusion**:
- The correct answer is **Option C: Both A and B**, as cells in the maturation phase show both increased cell wall thickness and protoplasmic modifications.
