what is PASSIVE TRANSPORT?
-Diffusion-is the tendency of molecules of either gases,liquids or solids to move from a region of lower molecular concentration until an equilibrium us reached,
this movement is cause by KINETIC ENERGY.
-OSMOSIS-is the diffusion of water through a semipermeable membrane from a region of higer water concerntration to a region of lower water concentration. In solution undergoing osmosis,only water(solvent)molecules move through the membrane.
Filtration- fluids and the substance dissolve in them are forced through cell membranes by hydrostatic pressure
