In the context of osmosis, what is a hypotonic solution?
A
A solution with the same solute concentration as another solution.
B
A solution with a lower solute concentration compared to another solution.
C
A solution that causes cells to shrink due to water loss.
D
A solution with a higher solute concentration compared to another solution.
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 hypotonic solution: A hypotonic solution has a lower concentration of solutes compared to another solution. This means that the water concentration is higher in the hypotonic solution.
Consider the effect on cells: When a cell is placed in a hypotonic solution, water will move into the cell due to osmosis, potentially causing the cell to swell and even burst.
Differentiate from other solutions: A hypertonic solution has a higher solute concentration, causing cells to lose water and shrink, while an isotonic solution has the same solute concentration as the cell, resulting in no net movement of water.
Apply this understanding to the given options: The correct description of a hypotonic solution is 'A solution with a lower solute concentration compared to another solution.'
