Potato Cylinder From The Distilled Water Solution
808 wordsPotato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month, but if they didn't have water to drink they will be dead within a week. Hoping to postpone the inevitable, their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor'...

Potato Into The Sucrose Solution
1,035 wordsTitle: Osmosis in Potato Cells I am going to investigate: the diffusion of water by osmosis in plant cells, when changing the concentrations of sucrose in water, and measuring the change of mass of pieces of potato left in the solution for twelve hours. I predict that I predict that the stronger the solution of sucrose the more mass the pieces of potato will loose. This is because the solution will be more concentrated than the solution in the potato. So the water in the potato will come out thr...

Potato Into The Solution
2,083 wordsOsmotic activity in potato cylinders Skill Area P: Planning Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato cylinders. Hypothesis: Osmosis is defined as the net movement of water or any other solutions molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell ...

Extra Water Onto The Potato Chips
1,262 words... After 30 minutes I drained out the solutions in the sink and placed all the chips on the paper towel in the order I had put them in the test tubes as to not confuse myself as to which chip came from which solution. 10. I dried each chip with the paper towel and then placed each one on the scales so that I could weigh them. 11. Each potato was measured accurately on the electronic scales and then the weights were recorded. 12. As I had time after doing the first set of results I redid the exp...

Potatoes In The Test Tube
749 wordsFinding out the Rate of Osmosis in a Potato After Being Left in a Solution. What are you trying to find out? I am trying to find out how much water has been diffused into a potato when placed in different strengths of solution. But before the experiment can take place I need to explore all areas in which could produce biased or inaccurate results. What can influence the results of the experiment? Temperature - The temperature in which the experiment is conducted can affect the experiment. If one...

5 Pieces Of Potato
507 wordsThe following is a short sample from this piece of coursework: ... els of sucrose solution to distilled water (see molarity table above) and I placed each of the mixtures into the correct beakers. 5. Then I weighed all the potato chips on an electronic balance (see results) and recorded the results. 6. I placed 5 pieces of potato into each beaker and left them for approx 36 hrs. 7. After this time I drained out the solutions from the beakers and I carefully placed them in order of molarity on a ...

30 Minutes The Potato Piece Needs
1,018 wordsGCSE Biology: Osmosis in a PotatoAimTo investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction 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 molecules. If we say that the percentage change when the potato is placed in the 1 M solution is x%. I predict th...

Potato In The 0 4 Molar Solution
1,422 wordsIntroduction. Osmosis is the net movement of water between water molecules from a weaker solution to a stronger solution through a semi-permeable membrane. Structure of a plant cell. What happens when a plat cell is placed in a solution weaker then the solution in a cell? Osmosis takes place. Water diffuses into the cytoplasm and vacuole through the selectively permeable membrane. When this happens the solution in the middle is more concentrated and the vacuole expands while the cytoplasm moves ...

Solution Concentration
324 wordsPlan: The aim of this investigation is to measure the rate of osmosis activity in a potato chip when placed in different solutions. Osmosis is the diffusion of water from a high water potential to a low water potential across a partially permeable membrane. Osmosis continues in this environment until a state of 'equilibrium' is achieved where the water gradient in one are is no different to another. The experiments I conduct will show the rate of osmosis between the potato chip and the solution....
