What is the difference between hypertonic and hypotonic solutions in terms of their effect on a cell?
A
A hypertonic solution causes a cell to swell, while a hypotonic solution causes it to shrink.
B
A hypertonic solution has a lower solute concentration than a hypotonic solution.
C
Both hypertonic and hypotonic solutions cause a cell to remain the same size.
D
A hypertonic solution causes a cell to shrink, while a hypotonic solution causes it to swell.
Verified step by step guidance1
Understand the concept of tonicity: Tonicity refers to the relative concentration of solutes in a solution outside a cell compared to inside the cell. It affects the movement of water across the cell membrane.
Define hypertonic solution: A hypertonic solution has a higher concentration of solutes compared to the inside of the cell. This causes water to move out of the cell, leading to cell shrinkage or crenation.
Define hypotonic solution: A hypotonic solution has a lower concentration of solutes compared to the inside of the cell. This causes water to move into the cell, leading to cell swelling or lysis.
Analyze the effects on cells: In a hypertonic solution, cells lose water and shrink. In a hypotonic solution, cells gain water and swell.
Compare the options: The correct statement is that a hypertonic solution causes a cell to shrink, while a hypotonic solution causes it to swell, as it aligns with the definitions and effects of hypertonic and hypotonic solutions.
