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.

∙ 13y ago1. Isotonic: When there is no movement of water in/ out of the cell, because it is in equilibrium.
2. Hypertonic: There is a higher concetration of solute outside of the cell and causes a flow of water from inside to outside; the cell will shrink.
3. Hypotonic: Higher concentration of solute within the cell and so water moves from out to in, causing it to swell up.

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.
What are the 3 types of cells where photosynthesis occurs?
Palisacle Mesophyll Cell, Mesophyll Cell and one other but i don't know it sorry
Effects of tonicity on hemolysis of red blood cells?
A 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, leading to hemolysis.
What correctly describes the normal tonicity conditions for typical plant and animal cells?
The animal cell is in an isotonic solution, and the plant cell is in a hypotonic solution
What is relative tonicity?
From NorthSeattle.edu (see link to the left):Tonicity1. 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.See the Web Links to the left for more information.
Ethanol and animal cell tonicity?
nothin much happens
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

Can you name 3 types of cell?

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.
What types of material can a fuel cell be made of?
There are 3 main types of a Fuel Cell. 1. Hydrogen Fuel Cell. This is the main one people use nowadays. 2. Solid Oxide Fuel Cell. 3. Alkaline Fuel cell. Made from Alkaline metals.
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.
