Answer

To identify the correct sequence of different stages of plant development, we can break down the process into three main stages: cell division, cell elongation, and cell differentiation. Here’s a step-by-step explanation of the correct sequence:

### Step-by-Step Solution:

1. **Cell Division**:
- The first stage of development in plants is cell division. This occurs in the apical meristem, where cells proliferate (multiply) to increase the number of cells. This is essential for the growth of the plant as it increases the overall cell count.

2. **Cell Elongation**:
- After cell division, the next stage is cell elongation. In this phase, the newly formed cells start to increase in size. This elongation is primarily due to the absorption of water, which leads to vacuolation (the formation of vacuoles within the cells). As the cells absorb water, they swell and elongate, contributing to the growth of the plant.

3. **Cell Differentiation**:
- The final stage is cell differentiation. During this phase, the elongated cells mature and develop specific functions. Differentiation allows the cells to become specialized for various roles within the plant, such as forming roots, stems, leaves, or flowers. This maturation process gives the cells their permanent size and function.

### Correct Sequence:
- Therefore, the correct sequence of stages in plant development is:
1. Cell Division
2. Cell Elongation
3. Cell Differentiation
