osmosis

a type of passive transport involving the movement of water molecules from high concentration of water molecules to low concentration of water molecules

why does water diffuse in osmosis

because the permeable membrane allows water molecules to pass through but restricts the movement of solute molecules such as ions or other molecules

where does water move from and to

from area of fewer solutes to an area of higher solutes- to even out ratio

what is the direction and rate of osmosis influenced by

the concentration of solutes on both sides of the membrane and the pressure exerted on the solution

what happens when the volume of of the solution increases

the higher solute concentration gains volume which leads to an increase in pressure

what is solute potential also known as

osmotic potential

what is solute potential

a measure of the concentration of solutes in a solution and the effect that it has on the movement of water across a selectively permeable membrane

where does the water move to and from in terms of water potential

from high water potential to lower water potential

what is water potential

the tendency of water to move from one area to another

what contributes to water potential

solute potential

what is the formula for solute potential

-iCRT

is solute potential negative or postive

negative, as solutes lower the water potential of the solution

the more concentrated the solute

the more negative the solute potential

does a hypotonic solution have a lower or higher concentration of solutes?

lower concentration

does a hypotonic solution have a higher or lower solution potential

higher

where will water move in a hypotonic solution

into the solution or cell

osmolarity

a measure of the total concentration of solutes in a solution

what is an osmole

a unit of measurement that represents the number of particles that contribute to the osmotic pressure of a solution

what can osmolarity compare

the effect of different solutes on the movement of water across a selectively permeable membrane

what does osmolarity affect

the direction and rate of osmosis
