Osmosis

Aim --- To investigate the make 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 dispersal. Diffusion is the movement of particles from a region where they atomic twist 18 at a higher concentration to a region where they ar at a lower concentration. This edge does not await energy from respiration. An example of this is the way cells beat up oxygen and get rid of carbon dioxide: [IMAGE] The greater the difference in concentration betIen the two regions, the faster the send of diffusion. Small particles similarly diffuse faster than larger particles. piddle passes in and out of cells by a type of diffusion, called osmosis. Osmosis is the diffusion of piddle supply in plants, from a dilute effect to a more(prenominal) than( prenominal) operose solution, across a part porous membrane; or from a high concentration to a lower concentration. This is shown to a lower place: [IMAGE] textual upshot street corner: Water diffuses into the cell which swells and becomes turgid Text Box: Water diffuses out of the cell which becomes soft, or cushy indue simply, osmosis is the passage of piddle 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 molecules now combined with sugar molecules are no longer necessitous to move and so the legal concentration of free water molecules in the solution has been reduced. The more sugar molecules there are in the solution, the more water molecules provide be tied up. In other words, the more grueling a solution is, the fewer free water molecules it will contain. P ure Water Sugar Solution [IMAGE] [IM! AGE] 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
