    Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

    both the lab group and the class average‚ there is evidence that osmosis did occur in the bags. The largest change in mass was in the 1.0M sucrose bag the mass went from 12g initially to 14.2g‚ this gained 2.2g‚ an 18.3% change in mass for the group data over the duration of the experiment. The 0.2M bag went from 10.2g to 10.9g a 6.9% change in mass; the 0.4M bag went from 12.1g to 12.2g .83% change in mass; the 0.8M bag went from 10.9g to 12.2g and an 11.9% change in mass. During osmosis water diffuses

    Potato Osmosis Lab

    The purpose of the lab was to investigate osmosis‚ which was successfully achieved because there was a change in the potato’s mass which was due to the net movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel

    Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

    Diffusion and osmosis are processes that are a constant in our lives‚ even though many don’t realize it. Medicaments such as Fervex can be drunk only after diffusion has taken place and the powder granules have diffused into the hot cup of water. On the other hand‚ every day we become unintentional witnesses of osmosis when the roots of the plants try to suck up the water from the soil (1). The purpose of this lab is to show clearly in an understandable way how diffusion and osmosis happen and to

    weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH. The controls in this experiment are that each sample had

    Experimental Laboratory Report: An investigation into the rate of osmosis Liana Gohery - 98332250 12/12/2014 Word count - ………3000……….. 1. Abstract This study was conducted to investigate the effect of concentration gradients on the rate of osmosis. Osmosis is the cellular transport of water‚ this study was conducted to show the significance of the rate at which this occurs. Dialysis bags were filled with three different concentrations of sucrose solutions and two with water. They were

    G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III. Table 1.1 | Initial | Final | % Change | A | 11.4 | 11.86 | 4.03% | B | 11.67 | 15.33 | 33.68% | C | 10.84 | 11.86 | 9.4% | D | 12.02 |

    Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We

    transport of materials in three semi-permeable membranes: dialysis tubing‚ eggs‚ and onion cells. Background Information 1. Diffusion is the movement of solutes from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in
