Cells can be placed in solutions with higher, lower, or equal concentration to the cell...
1. ISOTONIC:
- a solution with equal concentration to the cell.
- 0.9% NaCl solutions is isotonic to RBC (red blood cells).
- isotonic solutions cause no net gain or loss of water to a cell.
2. HYPOTONIC:
- solute concentration is greater on the inside of the cell (or: the outer solution has less concentration than inside).
- >0.9% NaCl solutions is hypotonic to RBC (red blood cells).
- causes swelling, could burst (lyse)
- net gain of water
3. HYPERTONIC:
- <0.9% NaCl solutions is hypertonic to RBC (red blood cells).
- net loss of water from the cell.
- solute concentration is greater on the outside of the cell (or: the outer solution is greater concentration than the inside).
- causes the cell shrink (crenation in RBC)

What is the concentration of material in a cell that affects the fluid volume and pressure within the cell?
Tonicity
The tonicity of solution between cell wall and cell membrane in a plasmolysed cell?
In a plasmolyzed cell, the tonicity of the solution outside the cell is hypertonic compared to the cell's internal environment. This causes water to move out of the cell, leading to the shrinkage of the cytoplasm and the detachment of the cell membrane from the cell wall. As a result, the cell experiences plasmolysis, where the cell membrane pulls away from the rigid cell wall due to the loss of turgor pressure.
How does tonicity relate to osmosis?
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.
What is the tonicity of a parasite?
Parasites do not have tonicity themselves, as tonicity refers to the osmotic pressure of a solution. However, parasites can be affected by the tonicity of their external environment. Parasites may have adaptations to survive in different tonicity environments to maintain their osmotic balance.
What is the tonicity of a bacterial cell?
Isotonic conditions will not change the cell in bacterial or an human cell. Because the water concentration in the cell equal.Hypotonic conditions will increase the solute in the cell because of the osmotic pressure inside the cell. Cell may burst if to much solute is inside the cell. Bacterial and human cell.Hypertonic conditions is said to have osmotic pressure. Because the concentration in the environment has an higher concentration than inside the cell so all the solute will drive out of the cell and cause it to dry out.
What is the concentration of material in a cell that affects the fluid volume and pressure within the cell?
Tonicity
What are the principles of tonicity?
The principles of tonicity include hypertonic solutions causing cells to shrink due to water leaving the cell, isotonic solutions maintaining equilibrium between water leaving and entering the cell, and hypotonic solutions causing cells to swell due to water entering the cell. Tonicity is related to the concentration of solutes compared to the concentration of solutes inside the cell.
What is a correct example of tonicity?
A correct example of tonicity is a red blood cell in a hypertonic solution, where the solution has a higher solute concentration than inside the cell causing it to shrink and undergo crenation.
What role does the cell wall play in tonicity?
gives shape to plant cells
What is the difference between osmolarity and tonicity?
Tonicity refers to the relative concentration of solute particles inside a cell, with respect to the concentration outside the cell. Osmolarity refers to the movement of water from the inside to the outside of a cell, and vice versa

3 types of tonicity on a cell?
The three type are hypertonic, isotonic, and hypotonic. Hypertonic is when the tonicity of the cell is lower than that of the surrounding liquid, isotonic is when the tonicity of the cell is equal to that of the surrounding liquid, and hypotonic is when the tonicity of the cell is greater than that of the surrounding liquid.
What is the tonicity of a parasite?
Parasites do not have tonicity themselves, as tonicity refers to the osmotic pressure of a solution. However, parasites can be affected by the tonicity of their external environment. Parasites may have adaptations to survive in different tonicity environments to maintain their osmotic balance.
What is the tonicity of normal saline compared to your blood?
What is the tonicity of you blood
Ethanol and animal cell tonicity?
Ethanol can disrupt the osmotic balance in animal cells by causing them to shrink or swell depending on the concentration of ethanol. At high concentrations, ethanol can lead to cell dehydration and damage due to its ability to denature proteins and disrupt lipid structures. This disruption in tonicity can impact cell function and ultimately lead to cell death.
What are the real world applications of tonicity?
Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. In other words, tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution.
