osmosis and diffusion
Title: Osmosis and Diffusion Background: There is so much movement through the membrane. ... Diffusion is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated. During diffusion a mass solution in a given volume gives it more place to concentrate, this is called concentration. Diffusion causes many substances to move across a cell membrane but does not require the cell to use energy. Osmosis is the diffusion of water through a selectively permeable membrane. ...
