An Investigation to look at Osmosis in plant Cells under different concentrations. Aim: Our investigation is to look at Osmosis and how it affects plant cells under different concentrations of salt solution. We will be using equal sized pieces of potatoes in different molar solutions and observing as well as weighing before and after to see what effects Osmosis has. Osmosis Theory: Osmosis involves the movement of water molecules from one solution of chemicals to another, separated from the first by a barrier that allows only the water molecules through. This is called a partially permeable membrane. Water molecules will always move from a less concentrated into a more concentrated solution to balance the numbers of water molecules on each side. They continue to do this until the two solutions are at the same concentration (or until pressure stops further movement.) Equipment: In the following experiment, I will be using * Test tubes to put...
