Tonicity
1. Tonicity of aqueous solutions (water with solutes, such as salt, dissolved in it) is based on cellular responses to that solution.
2. Solutions are isotonic if the cells or tissue neither shrink nor swell in response to immersion in that solution.
3. Solutions are hypertonic if the cells or tissue shrink in response to immersion.
4. Solutions are hypotonic if the cells or tissue swell in response to immersion.

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 a measure of a solutions ability to change the volume of cells by altering their water content?
tonicity
What type of tonicity will draw water from red blood cells or Elodea cells?
Salt/Salt Water
Why is the tonicity of a solution important?
TONICITY describes the degree to which a solution can exert an osmotic pressure on a membrane. Particles which can freely cross a membrane do NOT affect tonicity. This is because they will freely move in order to achieve equilibrium. Therefore, tonicity is dictated by the particles than can't cross the membrane (such as proteins, which are usually too large to cross, or highly charged particles). Non-permeable particles will therefore force water to cross the membrane towards them in order to achieve equilibrium - they can therefore be said to exert an osmotic pressure on the membrane.Solutions can be HYPERTONIC (i.e. the surrounding solution contains a larger concentration of these non-permeable particles than inside the cell, causing water to LEAVE the cell) or HYPOTONIC (i.e. the opposite, where water moves INTO the cell). They can also be ISOTONIC (there is equilibrium of the non-permeable particles, so no water moves).There is a very important distinction between tonicity and OSMOLARITY: osmolarity ALSO takes into account the particles that CAN cross the membrane (the permeable ones). So a solution could be both HYPEROSMOLAR and ISOTONIC at the same time - one set of particles will be able to freely cross the membrane, so there will no net change in cell volume.
Unit of relative permeability?
Relative permeability is dimensionless
What is the material parasite lives in human blood relative to the tonicity of the blood?
Isotonic.. No water is gonna move in or out
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 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 tonicity of normal saline compared to your blood?
What is the tonicity of you blood
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 role does the cell wall play in tonicity?
gives shape to plant cells
Do muscles maintain posture by the property of tonicity?
Yes, if you contract the right muscles.
