|
Diffusion
|
moving or spreading of molecules from a high concentration to a low concentration.
|
|
|
equilibrium
|
concentration is the same throughout.
|
|
|
osmosis
|
diffusion of water through a permeable membrane. NOTE:USES PASSIVE TRANSPORT!!!
|
|
|
permeable
|
things can pass through it
|
|
|
hypotonic
|
lower concentration
|
|
|
hypertonic
|
higher concentration
|
|
|
isotonic
|
both concentrations are the same.
|
|
|
Turgar pressure
|
water diffusing into a cell
|
|
|
cytolysis
|
burst because of the excessive water pressure
|
|
|
plasmolysis
|
water leaves the cell and it dries out
|
|
|
active transport
|
cell uses energy to move things in and out.
|
|
|
passive transport
|
cell uses no energy to move things in and out.
|
|
|
carrier molecules
|
helps things move to and from cells
|
|
|
facilitated diffusion
|
GLUCOSE!!
|
|
|
gated channel
|
channel that doesn't allow passing of molecules.
|
|
|
endocytosis
|
take in by engulfing
|
|
|
phaygocytosis
|
solid
|
|
|
pinocytosis
|
liquid
|
|
|
homeostasis
|
a balanced condition between a cell and the environment.
|
|
|
contractive vacuole
|
to prevent cytolysis(organelles remove water)
|
