DIFFUSION

MOVEMENT OF MOLECULES FROM AN AREA OF HIGH CONCENTRATION TO AN AREA OF LOW CONCENTRATION

PASSIVE TRANSPORT

PROCESS THAT MOVES MOLECULES WITHOUT THE USE OF ENERGY

CONCENTRATION GRADIENT

THE DIFFERENCE IN THE AMOUNT OF MOLECULES ACROSS A DISTANCE OR SPACE

EQUILIBRIUM

EQUAL CONCENTRATION OF MOLECULES THROUGHOUT A SPACE

OSMOSIS

PROCESS THAT ALLOWS WATER MOLECULES TO MOVE FROM HIGH TO LOW CONCENTRATIONS

HYPOTONIC

TYPE OF SOLUTION THAT WOULD CAUSE A CELL TO SWELL AND EVEN BURST (WATER MOVES INTO CELL)

ENDOCYTOSIS

PROCESS BY WHICH A CELL INGEST EXTERNAL FLUID, MOLECULES. OR OTHER LARGE PARTICLES

ISOTONIC

SOLUTION THAT WOULD CAUSE NO NET CHANGE IN MASS

FACILITATED DIFFUSION

TYPE OF PASSIVE TRANSPORT THAT USES A PROTEIN TO HELP PASS MOLECULES THAT CANNOT DIFFUSE ACROSS THE CELL MEMBRANE

CARRIER PROTEIN

MOLECULE THAT ASSISTS AND HELPS IN FACILITATED DIFFUSION

ACTIVE TRANSPORT

MOLECULE TRANSPORT THAT REQUIRES ENERGY TO GO "UP" A GRADIENT

HYPERTONIC

TYPE OF SOLUTION THAT WOULD CAUSE A CELL TO SHRIVEL AND DECREASE IN MASS

EXOCYTOSIS

PROCESS BY WHICH A SUBSTANCE IS RELEASED BY THE CELL THROUGH A VESICLE

PINOCYTOSIS

TYPE OF ENDOCYTOSIS IN WHICH THE SUBSTANCE ENTERING THE CELL IS A SOLUTE OR FLUID (CELL DRINKING)

PHAGOCYTOSIS

TYPE OF ENDOCYTOSIS IN WHICH THE SUBSTANCE ENTERING THE CELL IS A LARGE PARTICLE OR CELL (CELL EATING)
