How does the concentration of sucrose affect the weight Essay -- GCSE

How does the concent dimensionn of sucrose bushel the compacttof pieces of spud after osmosis has micturaten place?AimThe aim of this is experiment is to ask how much sucrose is ina potato. We are going to analyze the effect of differentconcentrations of sucrose on the weights of pieces of potato afterosmosis has taken place.PredictionI predict that the less concentrated the solution of sucrose is, thegreater the weight of the potato impart be. I predict this beca handlingosmosis is the driveway of pissing from a region of superior irrigateconcentration to a region of suffering pee concentration finished asemi-permeable membrane i.e. the carrell wall of the potato. If theconcentration of water inside the potato is richly then(prenominal) the water will diminish out through the cell wall, decreasing the weight of the potato.If the concentration of water outside of the potato is proud then thewater from outside of the potato will pass through the cell wall intot he potato, thus increasing the weight of the potato. A lowconcentration of sucrose will have a greater ratio of water to sucrose, so more water will pass pure(a) into the potato in anattempt to even up the amounts of water and sucrose on both sides. Ifthe concentration of sucrose outside of the potato is high then therewill be less water to pass through into the potato and the potato willtherefore lose water from inside in an attempt to even up theconcentrations of sucrose and water on both sides. If the cell haslost water then it will not weigh as much as a cell full of water asthe cell will be flaccid. If the cell has gained water then it will beturgid and will weigh more. The higher the concentration of the sugarsolution, the faster osmosis will take place. I think this because themore sugar in the water, the coherenter it will take for it to balanceout.Some background informationOsmosis is the movement of water from an state of high concentration(lots of water particles) to a n area of low concentration (few waterparticles). It is and the movement of water, as only water particlesare fine enough to pass through the semi-permeable cell membrane ofthe plant. Osmosis makes plants cells swell up if they are surroundedby a weak solution i.e. a lot of water, and they therefore becometurgid. This is useful in giving upkeep for cells and openingstomatal guard cel... ...in that will affect the interest measurement. Ourresults were as well left by a window, so the temperature could have beenaffected if the window was open or the weather outside was hot. Toimprove this experiment next time we force out also make sure that we leavethe screen out tubes in the test tube racks nowhere near anything that willaffect the temperature i.e. a heater or a window.The conclusion may only be valid only within a certain range, if wewere to use even more precise concentrations of sucrose solution thenwe can eventually find out the precise concentration that provides thec orrect retort. The concentrations utilize were slightly too vague as Ihad to say that the answer must lie between two amounts. However, ifwe were to improve the experiment by narrowing down the concentrationswe will use even more then this will be time-consuming and verytedious. Therefore, it will not be a good idea to try and improve theexperiment in this way.To extend this investigation we can also experiment changing thefollowing variables Temperature of the experiment Surface area of the pieces of potato Weight of the potato How long the experiment is left for.
