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)

∙ 9y agoTonicity is the relative concentration of solutions that determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution.

∙ 9y agoA hypertonic solution will cause the cell to shrink as water leaves the intracellular fluid due to osmosis. A hypotonic solution will lead to water crossing into the cell membrane, causing it to swell.

What is the concentration of material in a cell that affects the fluid volume and pressure within the cell?
Tonicity
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.
Which term describes the difference in the concentrations of a substance across a cell membrane?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
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.
Why do you use saline water when preparing a plate with blood agar?
TONICITY
Ethanol and animal cell tonicity?
nothin much happens
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 concentration of material in a cell that affects the fluid volume and pressure within the cell?
Tonicity
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
What role does the cell wall play in tonicity?
gives shape to plant cells
What is the tonicity of normal saline compared to your blood?
What is the tonicity of you blood
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.
What is the best type of tonicity in an environment of a red blood cell?
Isotonic solutions will maintain the normal volume of an individual red blood cell. A hypotonic solution will swell the cell, and a hypertonic one will shrink it.
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.
Which term describe the difference in the concentrations of a substance across a cell's membrane?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
Which term describes the the difference in the concentrations of a substance across cell membrans?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
Which term describes the the difference in the concentrations of a substance across cell membrane's?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
