Question

Incipient plasmolysis is the

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

Answer 1

The correct option is D Initial stage of plasmolysis.

When a living cell is placed in a sufficiently concentrated solution of a suitable agent, plasmolysis occurs. There are three stages of plasmolysis, incipient, evident and final plasmolysis. The point at which the protoplast is just pulled away from the cell wall at corners is called as incipient plasmolysis. When protoplast is completely detached from the cell wall, it is called as evident plasmolysis. When cytoplasm is found at the centre of the cell, it is called as final plasmolysis.

Thus, the correct answer is option D.
