What is a Hypotonic Solution?
What is a Hypotonic Solution?
- The concentration of the solute is higher than inside the cell
- The concentration of the solute is lower than inside the cell (correct)
- The concentration of the solute is the same as inside the cell
- A solution with no solute
When a cell is placed in a hypotonic solution, it will swell.
When a cell is placed in a hypotonic solution, it will swell.
True (A)
What occurs when a cell is placed in an Isotonic Solution?
What occurs when a cell is placed in an Isotonic Solution?
- The cell shrivels
- Water leaves the cell
- Water enters the cell
- There is no net movement of water (correct)
What is a Hypertonic Solution?
What is a Hypertonic Solution?
A plant placed in a hypertonic solution may wilt.
A plant placed in a hypertonic solution may wilt.
What happens to cells placed in a hypertonic solution?
What happens to cells placed in a hypertonic solution?
What is the concentration of the solute inside and outside a cell in a hypertonic solution with 10% solute inside and 20% solute outside?
What is the concentration of the solute inside and outside a cell in a hypertonic solution with 10% solute inside and 20% solute outside?
What is the concentration of solute in a solution described as isotonic?
What is the concentration of solute in a solution described as isotonic?
In a hypertonic solution with 40% solute inside the cell and 60% solute outside, the solvent will move _____ the cell.
In a hypertonic solution with 40% solute inside the cell and 60% solute outside, the solvent will move _____ the cell.
Study Notes
Solutions in Osmosis
- Hypotonic Solution: Has a lower solute concentration than the inside of the cell, leading to water entering the cell.
- Cell Swelling: Cells placed in a hypotonic solution swell due to osmotic pressure.
Isotonic Solution
- Equal Concentration: Solute concentration is the same both inside the cell and in the solution, resulting in no net movement of water.
- Stability: Injection of isotonic solutions results in no cell disruption.
Hypertonic Solution
- Higher Solute Concentration: This solution has a higher solute concentration than inside the cell, causing water to exit the cell.
- Cell Shriveling: Cells placed in a hypertonic solution will shrivel as they lose water.
- Plant Wilting: A plant in a hypertonic solution experiences water loss, leading to wilting.
Concentration Examples
-
Hypotonic Concentrations:
- 60% solute inside, 10% outside
- 25% solute inside, 20% outside
- 55% solute inside, 25% outside
- 40% solute inside, 30% outside
- 40% solute inside, 20% outside
-
Isotonic Concentrations:
- 50% solute inside, 50% outside
- 10% solute inside, 10% outside
-
Hypertonic Concentrations:
- 10% solute inside, 15% outside
- 18% solute inside, 75% outside
- 43% solute inside, 60% outside
- 10% solute inside, 20% outside (listed multiple times indicates multiple scenarios of hypertonicity).
Effects on Cells
- Hypotonic: Cells swell as water enters.
- Isotonic: No significant change in cell volume as water movement is balanced.
- Hypertonic: Cells lose water, shrink, and may become plasmolyzed in plants.
