What is the difference between hypertonic, isotonic, and hypotonic?

Question

And, which way will water flow if a cell is placed in each of these three solutions?

Answer 1

hypotonic=lower solute concentration, water into cell,hemolysis
isotonic= equal concentration, cell stays same
hypertonic= higher concentration, water out of cell, crenation

Answer 2

Let's say the cell is A. The water is B.
In hypertonic, B has higher particle concentration compared with A. This means diffusion will go A->B so there is water concentration equilibrium.
Isotonic solution, no change. Both concentrations are equal.
Hypotonic, B has lower particle concentration compared with A. So diffusion makes the water go into the cell for water equilibrium.
Hope that helps.

Answer 3

Hypertonic is more concentrated in solutes than solvent.
Isotonic means that solutes approx solvent concentration.
Hypotonic means solvent in which case water is present more abundantly than solutes.
For the second part suppose a cell had a water potential of -1400 kPa.
The convention states that pure water has a water potential of 0 kPa,the latter being the highest.
If you place the mentioned cell in a solution of water potential -2000 kPa(a hypertonic solution),water would diffuse across the cell mb of the cell into the solution until reaching a dynamic equilibrium.
Secondly,when you put that same cell in a hypotonic one,there will be no diffusion at all(at the macroscopic level).
Thirdly, if you place that cell in a hypotonic solution of say -700 kPa,water would now diffuse into the cell.

They are all different types of solutions: hypotonic: a solution which contains more solute than solvent (example: a lot of salt(solute) dissolved in water(solvent)) hypertonic: a solution which contains more solvent than solute (example: purified water--there's almost no solute dissolved in the solvent(water)) isotonic: a solution in which the solute and solvent are equally distributed--a cell normally wants to remain in an isotonic solution, where the concentration of the liquid inside of it equals the concentration of the liquid outside of it hope this helped ~honors biology student :^)

Answer 5

hyper = high
hypo = low
iso = same

(the words hyperactive and hypothermia can help you remember the difference between hypo and hyper).

If a cell is in an isotonic solution, it means that the salt concentration inside the cell is the same as outside.

If a cell is in a hypotonic solution, it means that the salt concentration outside the cell is lower than the salt concentration inside.

If a cell is in a hypertonic solution, it means that the salt concetration outside the cell is higher than the salt concetration inside.

Answer 6

isotonic is when the concentration of the molecules of X is equal on both sides..(inside and out of the cell)
hypertonic is when the concentration of molecules is higher outside ( the cell)
and ipotonic is when the concentration of molecules is lower inside...

if you put a cell on a hypertonic solution the cell will get "desinflated" because the water inside the cell will try to balance the solution surrounding it...
if placed on an hipotonic solution the surrounding solution will enter the cell and it will inflate...probably die.
isotonic..nothing happens normal flow of solutions....
mm if u did not understood just go >http://en.wikipedia.org/wiki/Image:Osmotic_pressure_on_blood_cells_diagram.svg
and look at that image..
i tried my best to make it very simple to understand.

Answer 7

If, in terms of water, two solutions are isotonic, they have the same concentration of water. The water will circulate evenly.
If, in terms of water, solution A is Hypertonic to solution B, solution A has a higher concentration of water than Solution B. If solution A is the cell, water will flow out of the cell.
If, in terms of water, solution A is Hypotonic to solution B, it has a lower concentration of water than solution B. The water will flow into the cell.

Answer 8

Let the two solution be A and B.

Let's say A is hypertonic to B. In this case, water molecules will 'flow' from B to A, until they reach equilibrium.

Isotonic basically means the same water potential. Which means there will be no change.

If A is hypotonic to B, then water molecules will 'flow' from A to B until they reached equilbrium.
