Net movement of molecules or ions from a region of high concentration to a low concentration
1 of 5
Facilitated diffusion
Diffusion that involves PROTIEN CARRIER MOLECULES to allow the passive movement of substances across plasma membranes
2 of 5
Osmosis
passage of water from a region where it has a higher water potential to a region where it has a lower water potential through a partially permeable membrane
3 of 5
Water Potential
pressure created by water molecules. It is the measure of the extent to which a solution gives out water. the greater the number of water molecules, the higher the water potential, the highest being zero (pure water)
4 of 5
Diffusion proportion
Surface area × difference in concentration / length of diffusion path
