    Investigation into finding out the Effect of the effect of osmosis In potato cells Introduction I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2)

    of osmosis of tap water of Solanum tuberosum L. Solanum tuberosum L.‚ also known as potato‚ was the selected plant to be tested because it was easy to measure the percentage change in mass due to the osmosis of water into the tissue. RESEARCH QUESTION How does the surface area to volume ratio of potato tissue (Solanum tuberosum L.) affect the rate of osmosis of tap water? HYPOTHESIS The smallest cube of potato (1x1x1)‚ having a higher surface area to volume ratio‚ will have the fastest rate of

    of Osmosis” The purpose of the lab was to discover‚ through osmosis‚ the concentration of sugar water in a potato. First‚ potatoes were cut into strips about 3 centimetres in length and six strips were individually massed. Next‚ the six strips were placed in 6 different Dixie cups‚ labelled A‚ B‚ Q‚ X‚ Y‚ and Z. Each of the Dixie cups were then filled just enough to cover the potato strips‚ with substances that matched the letters of the cups. About 24 hours later‚ the potatoes were taken out

    small molecules to pass through - the larger the organism‚ the smaller the surface area ratio.Therefore if ratio is too small it take molecules much more longer to enter cell. Prediction For the experiment‚ I expect to see different effects on potato samples depending on different water concentration: · After putting in dilute solution I expect their mass to increase‚ as effect of taking up water by osmosis - cell should become ‘turgid’. · Concentrated glucose solution - mass of potatoes samples
