| Diffusion | Movement of molecules from area of higher concentration to area of lower concentration. |
| Carrier | Protein that combines with a molecule & helps move it thru cell membrane. |
| Osmosis | Diffusion of water thru a semi-permeable membrane |
| Proteins | Cell membrane has _____ embedded in it for specific functions |
| Exocytosis | Cells secrete substances to outside by this process. |
| Semi | Permeability to only certain substances |
| Into | When you place a cell in a hypotonic solution |
| Higher | Most substances move from _____ to lower concentration. |
| Plasmolysis | Means water leaves a plant & it wilts. |
| Passive | Movement of materials through the membrane |
| Hydrophobic | Water fearing |
| Cholesterol | Part of cell membrane that regulates permeability. |
| Isotonic | Solution in which concentration of water is equal on both sides of membrane. |
| Hypertonic | A blood cell is placed in a solution & shrinks |
| Facilitated | Glucose moves across the cell membrane by the process of _____ transport or diffusion. |
| Impermeable | A membrane that doesn't allow any substances to pass thru. |
| Channel | Cell membrane protein that allows free passage of molecules thru cell membrane. |
| Hemolysis | When a cell is placed in a hypotonic solution & explodes |
| Mosaic | The cell membrane is called a fluid _____ model. |
| Turgid | Plant cell in a hypotonic solution |
| Filtration | Movement along a water pressure gradient |
| Plasma | The cell membrane is also called the _____ membrane. |
| Phospholipid | The cell membrane is mainly a _____ bilayer. |
| Membrane | Universal part (feature) of all cells |
| Pinocytosis | Cell drinking |
| Phagocytosis | Cell eating |
| Gradient | Differences in concentration from one side of membrane to the other |
| Adhesion | Type of cell junction that holds cells together where tissues stretch. |
| Endocytosis | Cells take in substances by vesicle formation. |
| Tight | Type of cell junction which is zipper-like & forms a barrier. |
| Hydrophilic | Water loving |
| Plasmodesmata | Junction which connects plant cell cytoplasm. |
| Transport | Movement from lower to higher concentration - active _____. |
| Enzymatic | Cell membrane proteins that catalyze a specific metabolic reaction. |
| Peripheral | Proteins that do not penetrate cell membrane and play a structural role. |
| Recognition | Cell ______ proteins help recognize self from non-self. |
| Selectively | The cell membrane only allows certain substances to pass thru - this means it is _____ permeable. |
| Active | Transport process which requires energy to move substances across cell membrane |
| Hypotonic | Type of solution in which concentration of water is greater outside cell. |
| Receptor | Cell membrane protein shaped to bind with a specific molecule. |
| Integral | Proteins embedded in cell membrane. |
| Wall | In plant cells |
