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)
