Verified step by step guidance

Understand the concept of plasmolysis: Plasmolysis occurs when a cell loses water in a hypertonic environment, causing the cell membrane to pull away from the cell wall.

Identify the conditions for plasmolysis: It happens when the solute concentration outside the cell is higher than inside, leading to water moving out of the cell by osmosis.

Compare solute concentrations: Analyze the given options to determine which scenario describes a hypertonic environment for the cell.

Recognize the correct condition: The cell will experience plasmolysis when the solute concentration inside the cell is less than the solute concentration outside the cell.

Apply the concept: Use this understanding to predict cellular behavior in different osmotic conditions, reinforcing the concept of osmosis and its effects on cells.
