Osmosis Investigation Planning Experimental Procedures Aim To investigate the effect of osmosis. Background Research In order to attain a working knowledge of osmosis and its effects, I looked through school textbooks together with some information I had obtained at the library. Many substances pass in an out of cells by diffusion. Diffusion is the movement of particles from a region where they are at a higher concentration to a region where they are at a lower concentration. This process does not require energy from respiration. An example of this is the way cells take up oxygen and get rid of carbon dioxide: The greater the difference in concentration betIen the two regions, the faster the rate of diffusion. Small particles also diffuse faster than larger particles. Water passes in and out of cells by a type of diffusion, called osmosis. Osmosis is the diffusion of water in plants, from a dilute solution to a more concentrated solution,...
