. Define the term plasmolysis


Best Answer

Explanation : 

  • Plasmolysis is the loss of water by cells in a hypertonic solution. 
  • When a plant cell is immersed in a hypertonic solution, it loses water. 
  • As a result of the drop in turgor pressure, the cell's protoplasm peels away from the cell wall, leaving gaps between the cell wall and the membrane, causing the plant cell to shrink. 
  • Cytorrhysis, or the total collapse of the cell wall, results from a prolonged drop in pressure.

Final Answer :

Plasmolysis is a common reaction in plant cells that have been exposed to hyperosmotic stress.
