Question

The cell given in the diagram below is showing shrunken protoplasm. Which one of the following is an INCORRECT statement regarding this cell?

• A. The cell has decreased turgor pressure and increased osmotic pressure
• B. The cell was placed in hypotonic solution
• C. The cell is plasmolyzed
• D. The cell was placed in hypertonic solution

Hint:

Plasmolysis always occurs in a {hypertonic solution}, never in hypotonic solution.

Answer 1

The Correct Option is B

Step 1: Identify the condition shown in the diagram.
The diagram shows a cell with shrunken protoplasm detached from the cell wall. This condition is known as plasmolysis.
Step 2: Understand plasmolysis.
Plasmolysis occurs when a plant cell is placed in a hypertonic solution. Water moves out of the cell by exosmosis, causing shrinkage of the protoplasm.
Step 3: Analyze each option.
Option (A) is correct because loss of water reduces turgor pressure and increases osmotic pressure.
Option (B) is incorrect because hypotonic solution causes endosmosis, not plasmolysis.
Option (C) is correct because the cell is plasmolyzed.
Option (D) is correct because plasmolysis occurs in hypertonic solution.
Step 4: Final conclusion.
The incorrect statement is that the cell was placed in hypotonic solution.
