The very first event in the sequential stage of development of a higher plant cell is

Options

A. Elongation
B. Plasmatic growth
C. Maturation
D. Senescence

Answer

To answer the question about the very first event in the sequential stage of development of a higher plant cell, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Plant Growth**:
- Plant growth involves a combination of cell growth and cell division. This is a continuous process throughout the plant's life.

2. **Identifying the First Event**:
- The very first event in the development of a higher plant cell is known as "plasmatic growth."

3. **Explanation of Plasmatic Growth**:
- During plasmatic growth, the size of the cell increases. This increase in cell size is crucial as it sets the stage for further differentiation of the cell.

4. **Differentiation of Cells**:
- Following plasmatic growth, the differentiation of cells occurs, which is essential for the development of specialized functions in the plant.

5. **Subsequent Events**:
- After plasmatic growth, the next steps include cell elongation (influenced by hormones like auxin), maturation (where cells become specialized), and finally senescence (the aging process where cells lose their ability to divide).

6. **Conclusion**:
- Therefore, the correct answer to the question is that the very first event in the sequential stage of development of a higher plant cell is **plasmatic growth**.
