Lab report of diffusion and osmosis
...ove through a semi or partially permeable membrane (a membrane that lets some things through but not others). An example of this type of membrane is a cell wall, like in a potato. Osmosis occurs when two things occur. One is if the cell has no water in it or has less water then the solution it is placed in. If this is the case then water will go from the solution, for it is the area of high water concentration, into the cell, for this is the area of low water concentration. If the cell has no water within it the cell is flaccid. As the water passes through the cell membrane, the cell fills with water and becomes turgid. Once the cell becomes turgid, no more water can enter the Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Diffusion results because of the random movement of particles. The diffusion of water into and out of a selectively permeable membrane is called osmosis. Because of the selectively permeable membrane, nothing but water and other very small particles can be diffused through osmosis. The cell membrane is similar...
