OSMOSIS AND DIFFUSION Flashcards
movement of solvent (liquid)
particles across a semipermeable membrane
from a dilute solution to the concentrated
solution
OSMOSIS
diffusion of solvent across a
membrane, the movement solvent
molecules from a region of lower solute
concentration to a region of higher solute
concentration
OSMOSIS
movement of water
from higher water concentration to lower
water concentration through a semipermeable membrane
OSMOSIS
process where the low concentration
solvent is the one who enters the
semipermeable membrane to balance the
concentration of the high concentration area
OSMOSIS
require semipermeable membrane that only let
the allowed molecules to pass
OSMOSIS
occurs in liquid medium
OSMOSIS
concentration of the solvent does not
become equal on both sides of the
membrane
OSMOSIS
−Depends on the solute potential
OSMOSIS
−Depends on the number of solute particles
that are dissolved in a solvent
OSMOSIS
seeks to equalize the solvent
concentration, but it does not achieve
equalization due to the limit it can only
absorb.
OSMOSIS
movement of solute molecules
from an area of higher concentration to an
area of lower concentration.
DIFFUSION
movement of
particles/molecules from an area of higher
concentration to lower concentration. The
overall effect is to equalize concentration
throughout the medium/system
DIFFUSION
−Doesn’t need a cell membrane can pass
through immediately;
Doesn’t require a semi
permeable membrane
DIFFUSION
equalize the concentration as long as
there is space
DIFFUSION
Any type of substance that moves from a
higher concentration to lower concentration
