| CELL | THE BASIC STRUCTURAL AND FUNCTIONAL UNIT OF ALL LIVING ORGANISMS |
| CELL THEORY | FUNDAMENTAL IDEA OF MODERN BIOLOGY: INCLUDES 3 PRINCIPLES (MUST KNOW ALL THREE) |
| PLASMA MEMBRANE | A SPECIAL BOUNDARY THAT HELPS CONTROL WHAT ENTERS AND LEAVES THE CELL |
| ORGANELLE | SPECIALIZED STRUCTURES THAT CARRY OUT SPECIFIC FUNCTIONS |
| EUKARYOTIC CELL | HAS A NUCLEUS AND OTHER MEMBRANE-BOUND ORGANELLES |
| PROKARYOTIC CELL | HAS NO NUCLEUS OR ORGANELLES |
| SELECTIVE PERMEABILITY | ALLOWS SOME SUBSTANCES TO PASS THROUGH AND OTHERS NOT TO |
| PHOSPHOLIPID BILAYER | TWO LAYERS OF PHOSPHOLIPIDS ARRANGED TAIL TO TAIL |
| TRANSPORT PROTEIN | HELPS TO MOVE SUBSTANCES OR WASTE THROUGH THE PLASMA MEMBRANE |
| FLUID MOSIAC MODEL | THE "SEA" CONCEPT OF THE PLASMA MEMBRANE |
| DIFFUSION | THE MOVEMENT OF PARTICLES FROM AN AREA OF HIGH CONCENTRATION TO AN AREA OF LOW CONCENTRATION |
| DYNAMIC EQUIIBRIUM | A CONDITION WHERE THERE IS CONTINUOUS MOVEMENT OF PARTICLES BUT NO OVERALL CHANGE |
| FACILITATED DIFFUSION | A FORM OF PASSIVE TRANSPORT THAT USES PROTEINS TO MOVE IONS OR SMALL MOLECULES ACROSS THE PLASMA MEMBRANE |
| OSMOSIS | THE DIFFUSION OF WATER |
| ISOTONIC SOLUTION | A SOLUTION WITH SAME CONCENTRATION AS THE CELL |
| HYPOTONIC SOLUTION | A SOLUTION WITH A LOW CONCENTRATION OF SOLUTE: CELLS SWELL |
| HYPERTONIC SOLUTION | A SOLUTION WITH A HIGH CONCENTRATION OF SOLUTES: CELLS SHRINK |
| ACTIVE TRANSPORT | MOVEMENT OF PARTICLES ACROSS THE CELL MEMBRANE BY USING ENERGY (AGAINST THE CONCENTRATION GRADIENT) |
| ENDOCYTOSIS | A PROCESS WHERE CELLS SURROUND A LARGE MOLECULE AND BRING IT INTO THE CELL: ACTIVE TRANSPORT |
| EXOCYTOSIS | A PROCESS WHERE CELLS SECRETE A LARGE MOLECULE AND EXPEL IT FROM THE CELL: ACTIVE TRANSPORT |
| PASSIVE TRANSPORT | MOVEMENT OF PARTICLES ACROSS THE CELL MEMBRANE WITHOUT THE USE OF ENERGY (WITH THE CONCENTRATION GRADIENT) |
