it is a type of diffusion

which is true about osmosis?

the cells shrink

which occurs when a hypertonic solution is added to cells?

sodium is able to diffuse thru the pores

1. why do you think there is no pressure change w glucose on both sides?

there is no net movement of water because the solute concentrations are the same

2. why do you think there is no pressure change w glucose on right and albumin on left?

double

If you double the concentration of a nondiffusible solute that is on one side of a membrane, the osmotic pressure will

20 MWCO

Which membrane did not allow Na+ Cl- to pass through?

hypotonic solution

the net movement of water would be into the cell in a

the concentration of non diffusing solutes

the variable that affects osmotic pressure is

toward solutes

water diffuses....

pressure above the left beaker

what do you think will be the pressure result of the current experimental conditions?

increased osmotic pressure

what effect do you think increasing the Na+Cl- concentration will have?

equilibrium is reached

when a solute is able to diffuse thru a membrane,
