Question

Which of the following conditions would likely INHIBIT plasmolysis in a plant cell?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Plasmolysis and Osmosis
 **Related Topics**: Plant cell structure, water potential, solute concentration
 **Prerequisites**: Understanding of osmosis, hypertonic, hypotonic, and isotonic solutions.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about conditions that inhibit plasmolysis.
  Plasmolysis is the process where the plant cell membrane pulls away from the cell wall due to water loss in a hypertonic environment.
**Method & Steps**:
 1. Understand Plasmolysis:
  Reasoning: Plasmolysis occurs when the water potential outside the cell is lower than inside the cell (hypertonic solution). Water moves out of the cell via osmosis, causing the cell membrane to shrink away from the cell wall.
  Formula/Rule: Water moves from a region of high water potential to a region of low water potential.
 2. Identify conditions that inhibit plasmolysis:
  Working: To inhibit plasmolysis, we need to prevent water loss from the cell. This can be achieved by placing the cell in a solution where the water potential is higher outside the cell than inside (hypotonic solution).  In a hypotonic solution, water will move into the cell, preventing plasmolysis.
  Key Point: The direction of water movement depends on the relative water potential of the inside and outside of the cell.
 3. Select the correct option:
  Result: Placing the cell in a hypotonic solution (option C) will prevent plasmolysis.
  Verification:  A hypotonic solution will cause water to enter the cell, maintaining turgor pressure and preventing the cell membrane from detaching from the cell wall.
 ## OPTION ANALYSIS
A :x: Increasing the concentration of solutes in the external solution will create a hypertonic environment, promoting plasmolysis.
B :x: A hypertonic solution will cause water to leave the cell, leading to plasmolysis.
C ✓: A hypotonic solution will cause water to enter the cell, preventing plasmolysis.
D :x: Decreasing the cell's internal solute concentration will make the cell more likely to lose water to a surrounding solution, promoting plasmolysis.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing hypertonic and hypotonic solutions: Remember that hypertonic solutions have a higher solute concentration than the cell, while hypotonic solutions have a lower solute concentration.
  2.Ignoring the direction of water movement: Water always moves from high to low water potential (or from hypotonic to hypertonic solutions).
 **Quick Tips**:
  1.Use the terms hypertonic and hypotonic to visualize the relative solute concentration.
  2.Remember that water follows the solutes; where there are more solutes, water will move to.
