A study of Osmosis in plant cells Introduction In my following investigation, I will be studying osmosis. Osmosis is the process whereby water molecules pass across a semi permeable membrane from a less concentrated solution in to a higher concentrated solution. Because the holes in the membrane are very small, only small molecules can pass through them. For example, water is a small molecule, and sucrose is a big molecule, only the water can pass through the semi permeable membrane. When the two solutions either side of the membrane are of equal concentrations, the water does not stop moving through the membrane, there is just a net movement from each side. If you have two solutions of different concentrations, the solution with the higher concentration is said to be hypertonic and the solution with the lower concentration is said to be hypotonic. When the concentrations of the two solutions are the same, it...
