In the context of osmosis, what is a hypertonic solution?
A
A solution that causes cells to swell due to water intake.
B
A solution with a lower concentration of solutes compared to another solution.
C
A solution with an equal concentration of solutes compared to another solution.
D
A solution with a higher concentration of solutes 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 hypertonic solution: A hypertonic solution is one that has a higher concentration of solutes compared to another solution, typically the inside of a cell.
Consider the effect of a hypertonic solution on cells: When cells are placed in a hypertonic solution, water moves out of the cells into the surrounding solution, causing the cells to shrink.
Differentiate between hypertonic, hypotonic, and isotonic solutions: A hypotonic solution has a lower concentration of solutes compared to another solution, causing cells to swell. An isotonic solution has an equal concentration of solutes, resulting in no net movement of water.
Apply this understanding to the given options: The correct description of a hypertonic solution is 'A solution with a higher concentration of solutes compared to another solution.'
