Investigate how the Concentration of a Sucrose Solution affects the Rat

Investigate how the Concentration of a Sucrose Solution affects the stray of OsmosisIntroductionDiffusion is the movement of particles from a advanced concentration to alow concentration until they are spread out evenly. An example ofdiffusion is when an thermobaric bomb is sprayed. The particles spread out fromthe high concentration at the nozzle into the rest of the room andthat is how the smell moves.Osmosis is the passage of water molecules from a weaker base to astronger settlement through a partially permeable membrane. Osmosis is atype of diffusion involving water - the water molecules move from aweak solution (with a high concentration of water) into a strongsolution (with a low concentration of water).The cell membrane in a plant cell is partially permeable - it hassmall holes that evict let in small molecules but not large ones. Thisallows water through and therefore allows osmosis.When the cell has all the water it can take inside of it the osmosisprocess stops. The water pushes up against the cell wall which isstrong enough to stop it bursting. The cell is large(p) and the plantneeds turgid cells to give it rigidity and allow it to stand upright.If the cell has not enough water in it, it is flaccid and doesntsupport the plant which goes limp.In order to make grow for my experiment I did a preliminary experimentto get an idea of how I would do my real experiment and what apparatusand solutions I would need. I weighed 11 potato handicaps and put theminto separate boiling tubes. I filled each boiling tube with adifferent concentration of a sucrose solution from 0 molars (water)through to 1.0 molar with 0.1M intervals in between. After 30 minutesI removed the potato chips and measured their mickle. I found that thechips in the concentrations of 0M to 0.2M had increase in mass andthe rest had decreased in mass. For my experiment I train chosen to usefive concentrations of sucrose solution - 0.0M, 0.1M, 0.2M, 0.3M and0.4M. I have chosen these c oncentrations for two reasons. Firstly theycover the point at which the increase in mass changes to a decreaseand therefore I can hopefully find the equilibrium where the massstays the same, and secondly they are all at equal intervals so itwill be easy and accurate to legislate a graph for my results.PredictionI predict that out of the five potato chips used in the experiment atleast two will... ...tato chipin the solution for different time periods. I could then compare thegradients of the lines of best fit for the 5 different times, and alsodraw graphs for each molarity across the 5 time periods. I could alsodo an experiment using the same concentrations as I did in thisexperiment, but measuring the mass of the potato chips after every 3or 4 hours until the mass stays the same, and see how long potatochips in different solutions took to reach a final mass and to see howlarge its mass would get. Finally I would like to do the sameexperiment as I did here, but stress it out on different types of plantsand compare the rates of osmosis of the different plants. This wouldgive an idea of which plants were more efficient at taking up waterand I could see what types of plants had the fastest rate of osmosis,and whether there was a link between the rate of osmosis in a plantand the habitat it exists in. For example I great power find that plantsthat live in hot, dry conditions have a faster rate of osmosis thanplants which live in cold, wet environments. These experiments wouldhelp give a rectify idea of how the rate of osmosis is affected by theconcentration of a solution.
