Investigation into osmosis in potato cells essay

This is because the cell is fully plasmolysed and no more water can leave the cell. In distilled water I think that the potato chips will swell because water enters their cells by osmosis.

Osmosis Investigation

Plant cells become "turgid" when they are put in dilute solutions. This is how the concentration is balanced. When plant cells are placed in concentrated sugar solutions they lose water by osmosis and they become "flaccid. Therefore, the chips in higher water concentrations will have a larger mass than in higher sugar concentrations.

When plant cells are placed in concentrated sugar solutions they lose water by osmosis and they become "flaccid. Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal.

The potato chip will be measured before it is put in the solution, and after. I can also predict that the weakest sugar solutions will give the least decrease in potato mass, this is because there is a smaller concentration gradient therefore less water will have to leave the potatoes to equalise the two regions.

The graph above shows a simple curve obtained when the concentration of the solution is plotted against the percentage change in mass.

This means that there will be a steady net flow into the stronger solution, of glucose causing this region to fill with water and Investigation into osmosis in potato cells essay it. When they take up water by osmosis they start to swell, but the cell wall prevents them from bursting.

To create a fair test certain aspects of the experiment will have to be kept the same whilst one key variable is changed. We call this incipient plasmolysis. For this particular investigation I think that the lower the concentration of the sugar solution in the test tube the larger the mass of the potato will be.

This will give me a varied set of results from which I hope to make a decent conclusion. Plant cells become "turgid" when they are put in dilute solutions. These cells are said to be plasmolysed. Therefore, the chips in higher water concentrations will have a larger mass than in higher sugar concentrations.

An example of a partially permeable membrane is visking tubing. When plant cells are placed in a solution which has exactly the same osmotic strength as the cells they are in a state between turgidity and flaccidity. Further information on potato plant cells: I have chosen to vary the concentration of the sugar solution.

When plant cells are placed in a solution which has exactly the same osmotic strength as the cells they are in a state between turgidity and flaccidity. To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size.

If any of the non-variables below are not kept constant it would mean it would not be a fair test. Doing all the tests at one temperature will control the temperature. Turgid means swollen and hard. This means that because the potato chips are full of starch they will absorb water when put into the distilled water, as this is the weaker solution with a high concentration.

When they take up water by osmosis they start to swell, but the cell wall prevents them from bursting. Osmosis occurs across a partially permeable membrane, with holes only small enough for water molecules to pass through and not larger ones like glucose.

Leaves are entirely supported by the turgor pressure that is created when a plant is well watered and all the contents of the cells start to push against the cell wall and thereby giving support to the plant tissue.

In the water itself, to a low concentration, i. Turgidity is very important to plants because this is what make the green parts of the plant "stand up" into the sunlight.

This is because the cell is fully plasmolysed and no more water can leave the cell. My reasons for this can be seen in osmosis when water diffuses into the cell from a weaker solution high water concentration into the stronger solution low water concentration.

The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other.

I predict that the higher the concentration of the sugar solution the lower the final weight of the potato chips. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other.

The contents of the potato cells shrink and pull away from the cell wall. These cells are said to be plasmolysed. For this particular investigation I think that the lower the concentration of the sugar solution in the test tube the larger the mass of the potato will be.

This is useful for the plant as it gives support for opening stomata guard cell. I will measure the mass in grams.Essay on Osmosis Investigation. Essay on An Investigation into the Factors which Affect Osmosis Osmosis in Potato Cells Essay Words | 5 Pages.

Osmosis in Potato Cells Aim === The aim of my experiment is to investigate the effect of glucose solution on osmosis in potato chips. I shall be observing how the mass of the potato chip. Osmosis Osmosis in plants cells. Place one potato piece into each of the test tubes.
