How Do Different Sugar Solutions Effect Osmosis In A Potato Chip?

8042 words - 32 pages

Osmosis is a type of passive transport. This means that it is a process that does not need any energy to take place.Partially permeable membranes (or sometimes called semi-permeable membranes) are very thin layers of material that allow certain things to pass through it while preventing other things from passing through.An area of high water concentration is a dilute solution of the substance added to it to water to alter its concentrationAn area of low concentration of water is a concentrated solution of the substance added to it to alter its concentration.Therefore, Osmosis is a name used to describe the movement of water from an area of high water concentration to an area of low water concentration through a partially permeable membrane or in terms of the solute, Osmosis is a name used to describe the movement of water from an area of low concentration to a high concentration through a partially permeable membrane.Osmosis can take place in three types of solutions.1. Isotonic Solution:2. Hypotonic Solution:3. Hypertonic Solution:Facilitated OsmosisSome solute molecules that are soluble in water cannot pass through the semi-permeable membrane because when they dissolve in the water, their molecule sizes become bigger so they are transported across the membrane by carrier proteins. A carrier protein will be embedded into the membrane and when these molecules come into contact with these proteins, the proteins changed shape and the molecules pass through and come out on the other side of the membrane.DiffusionDiffusion is also a type of passive transport so this also doesn't require any energy to take place. Diffusion is the spreading of certain particles across an area of high concentration to an area of low concentration. It doesn't involve a membrane and diffusion can happen through solids, liquids and gases. Unlike Osmosis, diffusion doesn't only happen to water particles, it happens to all types of substances. Once the molecules are even throughout the space, it is called Equilibrium.In liquids and gases, diffusion happens through a processcalled the Brownian Motion. This is the collision of particlesagainst each other. The way the substance diffuses is by itsparticles colliding against one another.Active TransportThis is exactly the opposite of Osmosis.With water, this is the movement of water from a low water concentration to an area of high water concentration through a partially permeable membrane and in terms of the solute active transport is the movement of water from an area of high concentration to an area of low concentration through a partially permeable membrane.Some solutes have a higher concentration inside the cell than outside so the have to cross the membrane against the concentration gradient. This means that they can't get in by using the method of osmosis or facilitated osmosis. They must enter by the process called active transport. The reason that it is called active is because it required energy from the cell because it...

Investigation to find the effect of different concentrations of sugar solutions on osmosis

1930 words - 8 pages can be seen in living cells. The cell membrane in cells is semi-permeable and the vacuole contains a sugar/salt solution. So when a cell is placed in distilled water (high water concentration) water will move across the semi-permeable membrane into the cell (lower water concentration) by osmosis, making the cell swell. This cell is now referred to as turgid. If done with potato cells the cells would increase in length volume and mass because of
