Conclusion In conclusion it was proven that on average, the potatoes that were in the test tube containing little to no sucrose solution gained in mass, and those that were in test tubes containing more or only sucrose had a decrease in mass. We weighed the tubes at specific time intervals to measure the rate of diffusion of water in each different solution. Solute concentration is also important for the survival of plants. In an experiment trying to find out the isotonic point of something, salt is not the best substance to use. Maintaining all variablesunchanged such as the pH, same size, and a constant temperature.

Osmotic pressure is the force that can be applied to prevent water from flowing in this fashion Morgan, Carter 2005. Measure their weight on an electronic balance5. Safety Considerations It is important for one to be careful using sharp instruments. At the point the graph crosses zero, which is about 1. This is why salting fields was a common, devastating war tactic because it would kill the crops in the field and create major food shortages! Consumers break sucrose down into two inconsistencies so they can be absorbed more easily onto the blood. Three different observations were made when testing the effects of osmosis on red blood cells—one for each test tube. Environmental factors could change results as well, if temperature is higher than room temperature, osmosis could occur faster than usual.

They were placed into the test tubes containing sucrose and were to be left on the test tube rack over a 24 hour radius. This process in turn causes the grass to dry out and die. Measure them as accurately as possible. This is the reason many students request us to handle their osmosis lab reports as we are always readily available when placing or following up an order.

If the potato cores mass decreases then the solution has a lower water potential than the solute. Methemoglobin is not a problem in adults since they have an enzyme that converts methemoglobin back to hemoglobin. Our results were not what we expected though. If the concentrations are unequal, the solution with the higher concentration is hypersonic, and the solution with the lower concentration is hypotonic. When the sucrose solution was at 0.

Potato Osmosis Lab Report Essay Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. If we were to do the experiment again and take the average of both sets of results then it may be more accurate as well. Sucrose is a carbohydrate found in food. All particles that pass through the plasma membrane by the process of diffusion do not require energy, so their movement is called passive transport. The bag is carefully blotted to remove any water spilled during the filling and then weighed and recorded for an initial mass. Hypothesis:I predict that if the potato cylinders where put in a sucroseconcentration where the water potential is higher than the waterpotential that of the potato it self that would cause the mass of thepotato to increase and if they had similar water potential there will beno change in mass. Diffusion is where the solutes move from an area of high concentration to a low concentration.

By filling dialysis tubing with different concentrations of. Put dried potatoes into the solutions for 10 hours e. We then observed the movement of carmine particles under the microscope, first with low power, and then on high power, and recorded the results. Data Processing:After having collected the data from the experiment the data will beprocessed. We can determine this by conducting an experiment in which involves the process of osmosis. Temperature of the osmosis setup The water was taken from the same source and the entire experiment was conducted at room temperature 25 ̊ C.

Osmosis is the key to understanding this issue. The part that has almost no weight change is the isotonic point. When a plant cell is placed in a solution containing a higher concentration of solute, the water in the cell would move towards the solution. Next, we rinsed the outside of the bag with water. Lab Report: Osmosis in potatoes. Free research that covers osmosis potato chip experiment-lab report osmosis potato chip experiment-lab report planning a questions what is the effect of. Then we submerged the potato slices inside the beakers which contained water with different concentration of dissolved salt.

When we submerged the potato in the solution, it would be better if we submerged the potatoes in the same time to make the results more accurate, we also could have peeled the potatoes completely in order to allow osmosis to happen faster and more efficiently. Safety Considerations It is important for one to be careful using sharp instruments. How do we make 1M sucrose solution? Since osmosis and diffusion are both part of passive transport, this means that they do not require energy or pumps. So the more percentage of the salt-water increases, the more water molecules move outside the potato passing through the semi-permeable membrane. This would mean that the potatoes would have the same time contacting with the sugar solution.
