What is the concentration of the solute in the solution is lower than the concentration inside the cell?
In the hypotonic solution the concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell. Therefore, there is more water outside the cell than inside. Cells in a hypotonic solution experience osmosis.
Is the solute concentration higher or lower in a hypertonic cell?
Tonicity and cells
|Tonicity of solution||Solute concentration||Water moves…|
|Hypertonic||Higher solute in solution than in cell||Out of the cell|
|Isotonic||Equal amounts of solute in cell and solution||Into and out of cell at the same time|
|Hypotonic||Lower solute in solution than in cell||Into the cell|
Is hypertonic high or low concentration?
The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.
How does a hypotonic solution differ from a hypertonic solution?
A hypotonic solution has a lower solute concentration than the fluid inside a cell. A hypertonic solution has a higher solute concentration than the fluid inside a cell.
Is sugar water hypertonic or hypotonic?
When sugar molecules are added to side B, it becomes hypertonic because there are more sugar molecules than side A. Water moves across the membrane, from the less concentrated (hypotonic) side A to the more concentrated (hypertonic) side B, until the concentration is equal on both sides.
Is grape juice hypertonic or hypotonic?
When the grape is placed in grape juice, an isotonic solution, water will not move across the semi-permeable membrane because water concentration is equal on both sides of it.
What does it mean for a solution to be hypertonic?
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. For example, hypertonic solutions are used for soaking wounds.
What is isotonic solution?
Isotonic solution: A solution that has the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.
What are isotonic solution and hypertonic solutions?
If a cell is placed in a hypertonic solution, water will be attracted to the environment and leave the cell, and the cell will shrink. In an isotonic environment, there is the same amount of water on each side, so there is no change in the size of the cell.
Is normal saline isotonic or hypertonic?
Normal saline is the isotonic solution of choice for expanding the extracellular fluid (ECF) volume because it does not enter the intracellular fluid (ICF).
