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

How does the ducking of sucrose affect the weightof pieces of spud afterward osmosis has taken place?AimThe aim of this is try is to investigate how much(prenominal) sucrose is ina potato. We are going to investigate the accomplishment of differentconcentrations of sucrose on the weights of pieces of potato afterosmosis has taken place. previsionI predict that the less concentrated the solution of sucrose is, thegreater the weight of the potato exit be. I predict this becauseosmosis is the movement of weewee from a orbit of superior water system systemconcentration to a region of low water concentration finished asemi-permeable membrane i.e. the cellular phoneular phone wall of the potato. If theconcentration of water inside(a) the potato is high consequently the water willpass out through the cell wall, fall the weight of the potato.If the concentration of water outside of the potato is high because thewater from outside of the potato will pass through the cell wal l intothe 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 thorough into the potato in anattempt to stock-still up the amounts of water and sucrose on both sides. Ifthe concentration of sucrose outside of the potato is high indeed 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 non weigh as much as a cell integral of water asthe cell will be flaccid. If the cell has gained water then it will beturgid and will weigh more. The higher(prenominal) the concentration of the sugarsolution, the faster osmosis will take place. I reckon this because themore sugar in the water, the longer it will take for it to offsetout.Some background informationOsmosis is the movement of water from an area of high concentratio n( voltaic piles of water particles) to an area of low concentration (few waterparticles). It is sole(prenominal) the movement of water, as only water particlesare small ample 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 support for cells and crackstomatal guard cel... ...in that will affect the next measurement. Ourresults were also left over(p) by a window, so the temperature could have beenaffected if the window was circularize or the weather outside was hot. Toimprove this essay next cartridge clip we can also make sure that we leavethe test 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 thecorrect answer. The concentrations used were meagrely too vague as Ihad to say that the answer must(prenominal) lie between two amounts. However, ifwe were to improve the experiment by tapered 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 subjoin 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.
