Diffusion

TermDefinition
Passive Transport The movement of dissolved materials across a cell membrane without using the cell's energy.
Diffusion A type of passive transport in which molecules from an area of high conentration to an area of low concentration.
Osmosis The diffusion of water molecules across a selectively permeable membrane from an area of high concentration to an area of low concentration.
Active Transport The movement of materials through a cell membrane using cellular energy (movement is from low concentration to high concentration).
Transport Proteins They are proteins that pick up specific molecules passing by the cell and carry them across the membrane.
Endocrytosis A form of active transport where the cell membrane takes particles into the cell by changing shape and engulfing the particles.
Selectively Permeable Membrane (Semi-Permeable Membrane) A type of membrane that allows some substances to pass through while others cannot. Ex: Cell membrane
Exocytosis A form of active transport where the vacuole surrounding particles fuses with the cell membrane, forcing the contents out of the cell.
Waste materials such as Carbon Dioxide Substances should be removed from cell
State of Equilibrium When the number of molecules outside a cell will be equal to the number of molecules inside the cell so diffusion stops.
Oxygen, water, and particles of food Substances that need to be able to move into cells
