Hypotonic v.s. Hypertonic?

A hypotonic solution is a solution having a lesser solute concentration than the cytosol. It contains a lesser concentration of impermeable solutes on the external side of the membrane. When a cell’s cytoplasm is bathed in a hypotonic solution the water will be drawn out of the solution and into the cell by osmosis. If water molecules continue to diffuse into the cell, it will cause the cell to swell, up to the point that cytolysis (rupture) may occur.

A hypertonic solution is a solution having a greater solute concentration than the cytosol. It contains a greater concentration of impermeable solutes on the external side of the membrane. When a cell’s cytoplasm is bathed in a hypertonic solution the water will be drawn into the solution and out of the cell by osmosis. If water molecules continue to diffuse out of the cell, it will cause the cell to shrink, or crenate.

Hypertonic Vs Hypotonic

There are three classifications of tonicness that one solution can have relative to another. The three are hypertonic, hypotonic, and isotonic.

Hypertonicity

A hypertonic solution is a solution having a greater solute concentration than the cytosol. It contains a greater concentration of impermeable solutes on the external side of the membrane. When a cell’s cytoplasm is bathed in a hypertonic solution the water will be drawn into the solution and out of the cell by osmosis. If water molecules continue to diffuse out of the cell, it will cause the cell to shrink, or crenate.

Hypotonicity

A hypotonic solution is a solution having a lesser solute concentration than the cytosol. It contains a lesser concentration of impermeable solutes on the external side of the membrane. When a cell’s cytoplasm is bathed in a hypotonic solution the water will be drawn out of the solution and into the cell by osmosis. If water molecules continue to diffuse into the cell, it will cause the cell to swell, up to the point that cytolysis (rupture) may occur.

Isotonicity

A condition or property of a solution in which its solute concentration is the same as the solute concentration of another solution with which it is compared.

In other words;

If the contents of the inside of the cell is called cytosol, and the solution on the outside of the cell has a higher concentration of sodium-chloride than the cytosol, then that outside solution would be said to be hypertonic. The water on the inside (in the cytosol) would be drawn to where it is less concentrated (the outside) by diffusion (osmosis) and the cell would shrivel (crenate), and possibly die. This is not good.

Hypotonic Vs Hypertonic

No. Hypotonic and hypertonic are not about the relative concentrations of solutes and water in a single solution, but the relative concentrations of solutes in two different solutions, such as one for inside a cell (cytoplasm) and one for the solution surrounding the cell. Hypotonic solution: [solutes in solution surrounding the cell] < [solutes inside the cell] Hypertonic solultion: [solutes in solution surrounding the cell] > [solutes inside the cell] Isotonic solution: [solutes in solution surrounding cell] = [solutes inside the cell]

Hypertonic- Cell shrinking

how to remember… when your hyper your all active but then you eventually crash(shrink)

hypotonic- cell swelling

isotonic- equilibrium

this is all your going to need to know

Some damn small things
