Osmosis Investigation The aim of my experiment is to find the effects of different solutions on plant cells. Osmosis is a form of diffusion, the movement of molecules to allow them to mix, which occurs in plants. When a cell containing a weak solution is next to a cell containing a stronger solution the water in the weaker solution moves towards the stronger solution. This is why I think that the pieces of potato in the concentrated solution will decrease in both weight and length. However, I believe that the potato will do the opposite and increase in length and weight. I cut 15 identical pieces of potato, measured and weighed them, and placed 3 in 0.25mol/l 3 in 0.50mol/l 3in 0.75mol/l 3 in 1.00mol/l and 3 in water inside a test tube. I ensured that each test tube had 10ml of liquid surrounding the potato. I gave it 3 days before...
