|---|---|
| A hypertonic solution has a higher concentration of solutes | Hypertonic |
| A hypotonic solution has a lower concentration of solutes | Hypotonic |
| Two solutions having similar solute concentration. They are said to be in equilibrium. | Isotonic |
| A process resulting from osmosis in which red blood cells, in a hypertonic solution, undergo shrinkage and acquire a notched or scalloped surface | Crenation |
| The disintegration of a cell by rupture of the cell wall or membrane | Lysis |
| A substance dissolved in another substance | Solute |
| The process in which particles in a fluid move from an area of higher concentration to an area of lower concentration, resulting in an even distribution of the particles in the fluid. Little or no energy is required. | Diffusion |
| Diffusion of a solvent (ie. Water molecules) thru a semi-permeable membrane from an area of lower concentration to an area of higher concentration | Osmosis |
| The movement of a substance across a membrane from a region of its lower concentration to a region of its higher concentration against a concentration gradient, using energy. This energy is supplied through respiration using ATP | Active Transport |
| The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through) | Selective permeability |
| A form of passive transport in which materials are moved across the plasma membrane by a transportprotein down their concentration gradient ; hence, it does not require energy | Facilitated Transport |
| The gradual difference in concentration of a dissolved substance in a solution between a region of high density and one of lower density | Concentration Gradient |
| The transport of fluids containing large particles and macromolcules across the cellular membrane inside membraneous sacs via vesicles | Vesicular Transport |
| Vehicular transport process that ejects substances from the cell interior into the extracellular fluid | Exocytosis |
| The cell ingests small patches of the plasma membrane and moves substances from the cell exterior to the cell interior | Endocytosis |
| A mechanism by which cells ingest extracellular fluid and its contents. It is a routine activity in most cells | Pinocytosis |
| It means "cell eating". he engulfing and ingestion of bacteria or other foreign bodies by phagocytes | Phagocytosis |
