Aim
To investigate a factor which might affect the movement of water in and out of cells.
Introduction
Osmosis is the movement of water in and out of cell membranes, which act as semi-permeable membranes. Semi permeable membranes are cells, which only take in a limited amount of a liquid. The water passes from a region of high to a region of low concentration, until the two are equal in concentrations of water.
If a cell is placed in water or a dilute solution than the cell will take in the water and it will swell up. …
