Methods of Passive Transport

Methods of Passive Transport Diffusion movement of substances from an area of higher concentration to an area of lower concentration occurs from random, constant motion of all molecules, atoms, and ions movement is due to kinetic energy Osmosis diffusion of water molecules across a semi-permeable membrane may cause hydrostatic pressure to build up in a cell hydrostatic pressure is also called osmotic pressure Dialysis diffusion of solutes across a semi-permeable membrane Facilitated Diffusion diffusion of solutes through channel proteins in the plasma membrane
