Maturation phase of cell is characterised by:

Options

A. Modification of protoplasm
B. Thickening of walls
C. Both (A) and (B)
D. None of these

Answer

To solve the question regarding the characteristics of the maturation phase of a cell, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Phases of Cell Growth**:
- Cells undergo three main phases during growth:
- Meristematic Phase
- Elongation Phase
- Maturation Phase

2. **Identify the Maturation Phase**:
- The maturation phase is the final stage of cell growth where cells undergo specific changes to reach their functional state.

3. **Characteristics of the Maturation Phase**:
- During the maturation phase, cells undergo:
- **Modification of Protoplasm**: This refers to changes in the cell's internal contents, which may include the development of organelles and accumulation of substances necessary for the cell's function.
- **Thickening of Walls**: This involves the deposition of materials (like cellulose, lignin, etc.) in the cell wall, making the cell walls sturdier and providing structural support.

4. **Evaluate the Options**:
- The question provides four options:
- A) Modification of Protoplasm
- B) Thickening of Walls
- C) Both A and B
- D) None of these
- Since both modification of protoplasm and thickening of walls are characteristics of the maturation phase, the correct answer is option C.

5. **Conclusion**:
- Therefore, the maturation phase of a cell is characterized by both the modification of protoplasm and the thickening of walls.

### Final Answer:
The correct answer is **C) Both A and B**.
