Question

Which of the following best describes plasmolysis in a plant cell?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [A]
## CONCEPT FRAMEWORK
	**Primary Concept**: Plasmolysis in plant cells
	**Related Topics**: Osmosis, Turgor pressure, Cell wall structure
	**Prerequisites**: Understanding of plant cell anatomy and the effects of water movement across cell membranes
## SOLUTION PATHWAY
**Given Information**:
		- Plasmolysis is a specific type of cellular response to water loss.
		- Involves the protoplasm and the cell wall of a plant cell.
**Method & Steps**:
	1. Identify the condition leading to plasmolysis.
		Reasoning: When a plant cell loses water, the protoplasm shrinks away from the rigid cell wall.
		Formula/Rule: Water movement is driven by osmotic pressure.
	2. Understand the physical changes in the cell during plasmolysis.
		Working: As the protoplasm shrinks, it detaches from the cell wall, creating a space between them.
		Key Point: This process is reversible if water is reintroduced.
	3. Conclude with the definition of plasmolysis.
		Result: The protoplasm's shrinking is the hallmark of plasmolysis.
		Verification: The description aligns with observed cellular behavior under hypertonic conditions.
## OPTION ANALYSIS
[A] ✓: Shrinking of the protoplasm away from the cell wall due to water loss. - This accurately describes the process of plasmolysis.
[B] :x: Swelling of the protoplasm due to water gain. - This describes turgor pressure, not plasmolysis.
[C] :x: Bursting of the cell wall due to excessive water intake. - This refers to cytolysis, which is the opposite of plasmolysis.
[D] :x: Movement of the cell nucleus towards the center of the cell. - This is unrelated to plasmolysis and pertains to other cellular processes.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing plasmolysis with turgor pressure: Remember, plasmolysis occurs due to water loss, while turgor pressure is due to water gain.
		2. Overlooking the role of the cell wall: Always consider the structure of plant cells when studying processes like plasmolysis.
	**Quick Tips**:
		1. Visualize the process: Draw diagrams of cells in isotonic, hypertonic, and hypotonic solutions to reinforce understanding.
		2. Relate to real-life examples: Consider how wilting plants exhibit plasmolysis when they lack water.
