Deposition of new materials inside the cell wall of cells starts in

Options

A. Meristematic phase
B. Reproductive phase
C. Maturation phase
D. Elongation phase

Answer

To answer the question "Deposition of new materials inside the cell wall of cells starts in," we will analyze the different phases of plant growth and development. Here’s a step-by-step solution:

### Step 1: Understand the Phases of Plant Growth
Plant growth is divided into three primary phases:
- **Meristematic Phase**: This is where cells are actively dividing.
- **Elongation Phase**: This is where cells increase in size.
- **Maturation Phase**: This is where cells reach their maximum size and do not grow further.

**Hint**: Remember the three phases of growth: Meristematic, Elongation, and Maturation.

### Step 2: Analyze the Meristematic Phase
In the meristematic phase, cells are characterized by:
- Continuous division
- Rich protoplasm
- Large nucleus

During this phase, there is no deposition of new materials in the cell wall; instead, the focus is on cell division.

**Hint**: Meristematic phase is all about cell division, not cell wall deposition.

### Step 3: Analyze the Elongation Phase
In the elongation phase:
- Cells undergo elongation due to the enlargement of vacuoles.
- There is significant deposition of new cell wall components, which is crucial for cell growth.

This phase is characterized by the increase in cell size and the addition of new materials to the cell wall.

**Hint**: Elongation phase is where cells grow larger and new materials are added to the cell wall.

### Step 4: Analyze the Maturation Phase
In the maturation phase:
- Cells attain their maximum size.
- There is no further increase in size or deposition of new materials.

This phase is focused on the maturity of the cells rather than growth.

**Hint**: Maturation phase is about reaching maximum size, not about adding new materials.

### Conclusion
Based on the analysis of the phases of plant growth, the deposition of new materials inside the cell wall of cells starts in the **Elongation Phase**.

**Final Answer**: Elongation Phase
