EXPERIMENT TO SHOW THAT THE CONCENTRATIONS OF LIQUIDS CAN AFFECT OSMOSIS ==> PRE-EXPERIMENT Background Information Osmosis is, by definition, the diffusion of water from a weaker, or more dilute concentration, to a stronger solution (i.e. down a concentration gradient) through a semi-permeable membrane, and it is this pinciple which I want to study. In order to observe any results, and draw a conclusion from them, I need to thoroughly research osmosis, and it's effect on plant and animal cells. This will allow me to design some preliminary experiments, and finally the main experiment, which may or may not prove that the concentrations of liquids have an affect on osmosis. Osmosis can occur in both plant and animal cells, and allows processes such as transpiration to occur. It also can change the structure of a cell, to a point where the cell can no longer function. Osmosis is the only way that water can diffuse...
