WHEN A SPIROGYRA FILAMENT IS PLACED IN A CONCENTRATED SALT SOLUTION FOR 30 MINUTES, THE CELL WOULD BECOME

• A. plasmolysed ✓
• B. turgid
• C. shortened
• D. elongated

The answer to the question is: A. plasmolysed

When a Spirogyra filament is placed in a concentrated salt solution for 30 minutes, the cell would become plasmolysed. Plasmolysis is the process in which a plant cell loses water and shrinks due to the loss of turgor pressure when placed in a hypertonic solution, such as a concentrated salt solution. In the case of Spirogyra, which is a type of green algae, the cell wall prevents the cell from bursting, but the protoplast (the living part of the cell) contracts away from the cell wall due to the loss of water, resulting in plasmolysis.
