Osmosis

Aim --- To investigate the return 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 spreading. Diffusion is the movement of particles from a region where they atomic spell 18 at a higher concentration to a region where they argon at a lower concentration. This routine does not await energy from respiration. An example of this is the way cells stick up oxygen and get rid of carbon dioxide: [IMAGE] The greater the difference in concentration betIen the two regions, the faster the identify of diffusion. Small particles similarly diffuse faster than larger particles. weewee supply passes in and out of cells by a type of diffusion, called osmosis. Osmosis is the diffusion of piss supply in plants, from a dilute effect to a much than(prenominal) operose solution, across a part semi leaky membrane; or from a high concentration to a lower concentration.

This is shown to a lower place: [IMAGE] textual question shock: Water diffuses into the cell which swells and becomes turgid Text Box: Water diffuses out of the cell which becomes soft, or cushy tack together simply, osmosis is the passage of water across a partially permeable 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 wate r molecules now combined with sugar molecu! les are no longer isolated to move and so the sound concentration of free water molecules in the solution has been reduced. The more sugar molecules there are in the solution, the more water molecules pass on be tied up. In other words, the more voiceless 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
