Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Define a hypertonic environment: A hypertonic solution has a higher solute concentration compared to the inside of the cell.
Analyze the water movement: Since water moves toward the higher solute concentration, water will move out of the cell into the hypertonic environment.
Predict the effect on the cell: As water leaves the cell, the cell will lose water and shrink.
Conclude that in a hypertonic environment, a cell will lose water and shrink due to osmosis.
