If there is a change in mass it is because water has entered or left the cell. So the experiment will be based upon the movement of water. The first potato chip will be placed in a zero percent solution. I believe that this will increase the mass. I believe this because the zero percent solution has a lower concentration then the cell sap inside the potato.
Osmosis Investigation How different concentrations of sucrose solution effect potato tissue. Aim How do different concentrations of sucrose solution effect potato tissue. Background Information Osmosis is the movement of water molecules though a partially permeable membrane from an area of high water potential to an area of low water potential. High Concentration Low Concentration The membrane lets small water molecules pass though but not large ones. The flow continues until the concentration becomes the same on the inside as on the outside.
The water will diffuse into the cell and the cytoplasm by osmosis. This means the cytoplasm pushes out against the cell wall as it expands slightly and the cell becomes firm or turgid. The overall effect over time is for each cell to increase slightly in mass and so the whole potato chip shows an increased mass. However, if you put a piece of potato into a sugar solution (where the water concentration around the chip is lower than the water concentration inside the cytoplasm in the potato's cells), then water will move out of the cells of the potato and into the... ... middle of paper ... ... and also would help me to spot any anomalous results more easily; with only two results, it can be difficult to tell which result of the two is anomalous. In future, I will try to collect three or four sets of results which should be a great help.
The effect of osmosis in potato cells with different concentrations of sucrose solution Aim: To test the effect of different concentrations of sucrose solution to osmosis in a potato cells by putting potato pieces in test tubes of water containing different concentrations of sucrose solution. Scientific Theory: Osmosis is defined as the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration. In a high concentration of water the amount of solute (e.g. sugar) is low. This could be called a weak or dilute solution.
This is due to osmosis. Osmosis is the diffusion of water from a... ... middle of paper ... ...also have an assistant to help me remove and place the potatoes in the solutions so that they all had equal amounts of time in their solutions. I can not make my experiment perfect as the are some limitations to my equipment. To obtain more evidence with osmosis I could improve certain addition aspects like the amount of solution in the test tubes, so that you could get results on whether the amount of solution affects the amount of osmosing a potato chip can do. Some potatoes could have more sugar in than others, so to extend my investigation I could produce results on which potatoes have more protein in.
Moreover, there are several new alternative coming out to recycle and reuse the potatoes waste. For example, there is a potential for potato peel to be a bio-active ingredient for the bio-pharmaceutical (Teagasc, 2014) as a fiber nutrient and can be used in combination with flour. Indeed, “Muffins with peels were darker, lower in height, and more resistant to compression” (p. 15, l. 4). (Arora, Camire,
[IMAGE][IMAGE][IMAGE][IMAGE] [IMAGE] This is a diagram showing where water from the dilute solute solution on the left passes through the semi- permeable membrane and moving into the high concentrated solute solution on the right. If we add a potato tissue into a diluted solute solution, this makes the solute solution have a higher water potential compared to the potato tissue. Therefore the water from the surrounding solute solution will move into the potato chip to try and balance the water. This makes the potato chip to rise in mass by increase in water. When the cells have gained lot of water and they are strong, we call these cells turgid.
copybook.) Hypothesis- If the concentration of sucrose increases, then the mass of the potato will decrease. However, if the concentration of the solution in the beaker is less than that of the potato (such as distilled water), then the mass of the potato will increase. So, as the concentration of sucrose increases the rate of osmosis increases. Variables- Independent variable: the concentration of sucrose solution in which the potato will be placed: o Distilled water o 20% sucrose solution o 40% sucrose solution o 60% sucrose solution Dependent variable: the change in mass of the potato after the experiment by osmosis.
If a potato cell was placed in the same circumstances the cells would increase in length, volume and mass because of the osmotic effects. If the same potato cells were placed in a solution with a low water concentration, then the effects would be the opposite - water would move out of the cell into the area of lower concentration, the water. Thus, the potato chip will decrease in length, volume and mass. In more extreme cases, the cell membrane would break away from the cell wall and the cell is then known as plasmolysed. The higher the concentration of water in the external solution, the higher the amount of water that enters the cell by osmosis.
Experiment to Find the Reaction of Potato Chips in a Salt Solution Aim: to find a reaction of potato chips in a salt solution. Hypothesis: I predict that the potato will change in mass. The difference will occur in accordance to the difference of concentration of the salt solution each potato chip is submerged in. The cause of this change in mass is called osmosis. Osmosis is the movement of water through cells in plants.
