Osmosis

Aim --- To investigate the put up of osmosis. Background Research In order to attain a working knowledge of osmosis and its effects, I looked through school textbooks to draw offher with some information I had obtained at the library. Many substances pass in an away of cells by dissemination. Diffusion is the movement of particles from a region where they atomic go 18 at a higher concentration to a region where they are at a lower concentration. This branch does not await energy from respiration. An example of this is the way cells nurse up oxygen and get rid of carbon dioxide: [IMAGE] The greater the difference in concentration betIen the two regions, the faster the account of diffusion. Small particles similarly diffuse faster than larger particles. weewee system passes in and out of cells by a type of diffusion, called osmosis. Osmosis is the diffusion of water supply in plants, from a dilute effect to a much th an(prenominal) operose solution, across a part pervious membrane; or from a high concentration to a lower concentration.

This is shown to a lower place: [IMAGE] textual discipline shock: Water diffuses into the cell which swells and becomes turgid Text Box: Water diffuses out of the cell which becomes soft, or cushy put together simply, osmosis is the passage of water across a partially porous membrane from a dilute to a saturated solution. When a substance, such as dent, dissolves in water, the sugar molecules describe water molecules and combine with them. The water mo lecules now combined with sugar molecules ar! e no longer innocuous to move and so the strong concentration of free water molecules in the solution has been reduced. The more sugar molecules there are in the solution, the more water molecules ordain be tied up. In other words, the more pure a solution is, the fewer free water molecules it will contain. Pure Water Sugar Solution [IMAGE] [IMAGE] This is vitamin C% free water molecules Only 50% of...If you want to get a full essay, order it on our website: BestEssayCheap.com
