Osmosis lab report 1 -a f f e c t o f c o n c e n t r a t i o n o n t h er a t e o f o s m o s i sprepared for:biologyprepared by:abdullrhman zakidate:1/12/2012: as the concentration of sucrose increases the difference in mass ofpotato will increase since sucrose is a hypertonic solution whichmeans that it has a higher amount of particles. This particular solution is saltwater, where the water is the solvent and the salt is the solute what occurred here was osmosis the cells inside the potato have had the water sucked out of them by the high concentration of salt in the water of the surrounding dish this means the water inside the potato cells have passed through the.
Published: mon, 5 dec 2016 the purpose of this investigation is to examine the effect of varying the concentration of a sugar solution (sucrose) on the amount of osmotic activity between a potato piece and the solution. The cooked potato cells are dead and so do not undergo osmosis so no water is drawn in and the salt remains dry in the case of the 3rd potato, as there is no salt, the cells do not develop. Potato in water with no sugar weighed the highest after 30 minutes, 302g potato in water with 40g sugar weighed the lowest, 285g but still increased the rate of osmosis is the highest in the water with no sugar and lowest in the water with the highest amount of sugar. 0 5 a student investigated the effect of different sugar solutions on potato tissue this is the method used 1 3add 4 use your graph in figure 3 to estimate the concentration of the solution inside the potato cells [1 mark] concentration = mol dm−3 0 5 5 the results in table 2 show the percentage change in mass of the.
Make one salt water solution, one sugar water solution, and for the third solution, simply use tap water make three thin potato slices — 1/2 cm thick place each potato slice into each of the solutions, and leave the slices in the solutions for a half hour. A single layer of plant cells is placed on a microscope slide and either distilled water or 5% sodium chloride solution is added to the cells osmosis will occur resulting in either turgid cells or plasmolysed cells. Practical work for learning remove the potato from the sugar (sucrose) solution dry it on a paper towel and weigh it if the concentration of the solution inside the potato cells is different from the concentration of the surrounding solution, there will be overall movement of water by osmosis.
Solution (02moll-1) there was an increase in the mass of the potato chips for the higher concentrations of sugar solutions (04moll-1 to 08moll-1) there was a decrease in the mass. Best answer: this is an experiment to demonstrate osmosis the sugar solution is more concentrated (has a lower water potential, or water concentration) than the potato cells therefore water should be drawn out of the potato cells by osmosis (the potato cell membranes are semi-permeable, or partially permeable. Of a potato cell students’ sheet be careful to mix the water and the more dense strong sugar solutions thoroughly add a sixth tube of water to complete the series label each solution and another tube to match eg 2 tubes labelled 08m, 2 tubes labelled 04m etc. The water from inside the potato moves out to the solution, causing the potato to shrink and to lose its 'turgor pressure' the more concentrated the salt solution, the bigger the difference in size and weight of the potato slice suppose an animal or a plant cell is placed in a solution of sugar or salt in water this means that if a.
In the water is much greater than inside of the potato cell the potato in the sugar solution stayed in its original size because the concentration is equal the potato swelled in the water because the concentration is greater on the inside than the outside of potato cell these results show that the water molecules inside the cell of the. The potatoes placed in hypertonic solutions lost mass (047, 029, 058) because the glucose in the solution moved from a higher concentration to lower concentration, passing through the membrane into the cells and shrinking them. - osmosis in potato cells in this investigation i will be investigating the amount of osmosis in potato cells and whether osmosis and potato mass changes in different strengths of sugar solutions i will do this by putting a constant amount of potato in solutions with steadily increasing sugar contents. As the concentration of the sugar solution increases from 02 to 04 mol l-1 the potato chip loses more and more mass because the difference in water concentration between the inside of the potato cells and the surrounding solution is increasingly different.
Sugar solution on potato cells how sugar solution might affect potato cells introduction: in this experiment, i am going to investigate the effect of changing the concentration of sucrose solution on the rate of osmosis in potato cells. Assuming that it's a very high concentration sugar solution, the sugar solution would have a lower water potential than the cells of the potatothrough the process of osmosis, water will move from a region of high water potential ('concentration') to low water potential. An investigation to determine the concentration of sugar inside potato cells - download as word doc (doc), pdf file (pdf), text file (txt) or read online scribd is the world's largest social reading and publishing site. Gcse biology: osmosis in a potato aim to investigate the effect of placing a piece of potato in a given strength of sugar solution prediction i predict that, as the solution becomes more concentrated the more the cell will shrink, as the water, of higher concentration inside the potato cells, flows down a concentration gradient into the solution, which has a lower concentration of water.
In the 15 and 2 molar sugar solutions the potato has higher water potential that the sugar solution so water molecules from the potato cells would have moved into the sugar solution, this made the potato cylinders float to the top of the solution rather than stay at the bottom of the beaker because it became lighter. The level of sugar solution in the potato cavity rises after some time due to the entry of water into the sugar solution through the selectively permeable membrane of the cells of the potato conclusion. Cell membrane and transport 1 cell membrane and transport 1 a) name and describe the process that allowed the potato cells to gain and lose mass when placed in the sugar solutions (2 marks: 1 mark for name 1 mark for description) to the cytoplasm of the potato cells (1 mark) ≈ 135 % sugar solution change in mass (%) sugar. To investigate the effect to the potato cells in the different solute concentration water essay a pages:3 words:766 this is just a sample we will write a custom essay sample on to investigate the effect to the potato cells in the different solute concentration water specifically for effect of sugar solution on potato chips osmosis.
