hypotonic solution
describe an hypotonic solution:
what is happening to the red blood cell & cell in beaker?
what is happening to the plant cell?
isotonic solution
describe an isotonic solution:
what is happening to the red blood cell & cell in beaker?
what is happening to the plant cell?
hypertonic solution
describe an hypertonic solution:
what is happening to the red blood cell & cell in beaker?
what is happening to the plant cell?

Explanation:

• Hypotonic Solution: A solution with a lower solute concentration compared to another solution (e.g., inside a cell). For red blood cells in a hypotonic solution, water enters the cell (osmosis) causing it to swell and potentially burst (hemolysis). For plant cells, water enters, making the cell turgid (due to the cell wall preventing bursting).
• Isotonic Solution: A solution with the same solute concentration as another solution. Red blood cells in an isotonic solution have no net movement of water (osmosis is balanced), so the cell shape remains normal. Plant cells in an isotonic solution also have no net water movement, and the cell maintains a normal, not overly turgid or plasmolyzed state.
• Hypertonic Solution: A solution with a higher solute concentration than another solution. Red blood cells in a hypertonic solution lose water (osmosis), causing them to shrink (crenation). Plant cells lose water, and the plasma membrane pulls away from the cell wall (plasmolysis).

Answer:

• Hypotonic Solution:
• Description: A solution with lower solute concentration than the cell's interior.
• Red Blood Cell: Swells (may burst - hemolysis).
• Plant Cell: Becomes turgid.
• Isotonic Solution:
• Description: A solution with equal solute concentration to the cell's interior.
• Red Blood Cell: Maintains normal shape (no net water movement).
• Plant Cell: Maintains normal (not overly turgid or plasmolyzed) state.
• Hypertonic Solution:
• Description: A solution with higher solute concentration than the cell's interior.
• Red Blood Cell: Shrinks (crenation).
• Plant Cell: Undergoes plasmolysis (plasma membrane pulls away from cell wall).
