Term Definition
Diffusion The act of atoms moving from an area of high concentration to an area of low concentration.
Facilitated Diffusion The process by which substances are transported through the cell membrane by means of protein carrier molecules.
Osmosis The diffusion of water through a semipenetrable membrane
Endocytosis The process through which the plasma membrane folds in on itself to bring a substance into the cell.
Exocytosis The transport of a material out of the cell by means of a sac or vesticle that first engulfs the material before it is expelled through an opening in a membrane.
Selective Permeability When proteins choose to include or exclude certain molecules.
Active Transport The movement or molecules or ions across a cellular membrane from lower to higher concentration.
Hypertonic Solution A solution with a higher salt concentration than normal body cells so that the water is drawn out of the cells by osmosis
Hypotonic Solution Any solution with a lower salt concentration than body cells so that water flows into the cells by osmosis.
Isotonic Solution A solution with the same osmotic pressure as blood.
