Incipient plasmolysis is

Options

A. Last stage of plasmolysis
B. Mid stage of plasmolysis
C. Zero hour for inception of plasmolysis
D. Intial stage of plasmolysis.

Answer

**Step-by-Step Solution:**

1. **Understanding Plasmolysis**: Plasmolysis is a process that occurs when a plant cell loses water in a hypertonic solution, causing the cell membrane to pull away from the cell wall.

2. **Stages of Plasmolysis**: There are three stages of plasmolysis:
- **Incipient Plasmolysis**: This is the initial stage where the protoplast (the living part of the cell) begins to separate from the cell wall. At this point, the protoplast is still partially attached to the cell wall but is starting to pull away.
- **Evident Plasmolysis**: In this mid-stage, the protoplast is more significantly detached from the cell wall.
- **Final Plasmolysis**: This is the last stage where the protoplast is completely detached from the cell wall and the cytoplasm may be found at the center of the cell.

3. **Identifying Incipient Plasmolysis**: The question asks specifically about incipient plasmolysis. It is defined as the stage where the protoplast is just beginning to pull away from the cell wall, indicating that it is the initial stage of plasmolysis.

4. **Conclusion**: Based on the definitions and stages discussed, incipient plasmolysis is correctly identified as the initial stage of plasmolysis.

**Final Answer**: Incipient plasmolysis is the initial stage of plasmolysis.
