Procedure three: //Elodea// leaf... . . Run a virtual version of the OLD AP lab at [|The Biology Place]. The processes of diffusion and osmosis account for much of the passive movement of molecules at the cellular level. In this laboratory, you will study some of the basic principles of molecular movement in solution and perform a series of activities to investigate these processes.
