|
|
Diffusion
|
A type of passive transport (spontaneous), therefore, it is a net movement of molecules in and out of the cell across the cell membrane along a concentration gradient (higher concentration to lower concentration)
|
|
Facilitated Diffusion
|
When molecules move (diffusion) via special transport proteins found within the cell membrane |
|
Osmosis
|
tendency of water to floe form a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances across semipermeable membrane |
|
Isotonic
|
Having equal tension or pressure
|
|
Hypertonic
|
Higher Concentration
|
|
Hypotonic
|
